Ok I took the valve cover off and the problem became very clear. One of the rockers fell off. I was able to press down the valve by hand and snap it back in to place. But how did this happen in the first place I wonder? I did JUST adjust the valves, they seemed too tight, so by internet specs, I...

It was running on and off for a over an hour the day this happened, however there is zero crud anywhere, so it seems very unlikely it would be overheating. I'll have to take the carb off again, then I can take the head off completely and take a closer look. If it is just some crud, do I just...

Did some poking around tonight. Double-checked the spark plug. Either this plug is mint, or I don't understand spark plugs. So I'm assuming its not the plug. Then I finally got around to popping the flywheel off. The key looked perfect, no sheering or gaps or looseness or anything like that...

I didn't check the key yet no. It seems strange that it would be that though. The machine ran - not perfect - but pretty good for an hour straight and suddenly it forgets how to run. I'll see if i can check the key Friday just for the hell of it. And I'm thinking ill replace the plug too since...

Yup I cleaned the carb the other day, took it all apart, sprayed everything. The tank looks totally clean and has seen several tanks of fresh gas so theres no old fuel anywhere. Would a dirty carb cause backfiring out the exhaust?

It was misfiring, the issue is that the mic on the phone doesn't pick it up. It's clearly missing and the whole machine kind of shake-rotates when it misses. It's doing it every couple of seconds. I need a better camera & mic to pick it up though. ALL THAT SAID, there have been some...

Ok I was able to properly adjust the valves tonight. They were both a little too tight, but not too bad. Put it back together, fired it up, zero change. I'm really running out of ideas. I guess theres that keyway thing people have mentioned. Although this machine is so new, I doubt that would...

The drama continues. So last night I went to check out the valves. I was expecting them to be too loose, because thats what I always see on youtube. But turns out mine were too tight. Very tight. So I tried loosening them. And wouldn't you know it, the tip of my T10 socket snapped right off...

It is definitely misfiring a lot, the tiny mic on the iphone camera doesn't capture the sound great. If you could hear it in person, you would not say it sounds fine.

I'm watching valve rocker adjustment videos on youtube right now. Looks easy enough, I guess that will be the next thing I try. I do own feeler gauges, but I have no glue where they are, I'll have to search for them first.

Whaaaaaat a shitshow today turned in to. The first thing I did was start up the machine and experiment with blocking the air intake by different amounts. It didn't seem to have any affect on how the machine ran. MAYBE a tiny bit smoother with it half covered, but it still misfired. No...

The mic on my camera doesn't capture the sound perfectly. So it does improve once it warms up, it never gets good. Its always misfiring/hunting. And with the new carb, it also has an awful startup. I didn't see a filter in the fuel tank and now I think its full, or close to it. I'll see if I can...

Doesn't it seem unlikely that the original carb was dirty, and the brand new one is also dirty? Seems like in this scenario where I've gone through two carbs, the air leak would be the more likely problem, no?

Ok well i disagree with some of what you say, but this part I don't understand at all: I don't know what you mean here or what you are suggesting I do?

GAH! Update: total failure! The mower behaves the exact same way, rough starts and sputtering/misfiring while running! I put the new carb in there, with the gasket that the old carb was missing. I also replaced the short little fuel line it has. After mowing half my lawn with the same poor...

Ok I modified the two springs tonight and the flap seems to be much tighter. The hook end that hooks on to the body of the mower, I basically cut the 90° off and then bent a new 90° angle into the new end of the spring. Basically pre-tensioning the spring so it pushes harder. It was kind of a...

Hmm I guess I worded this poorly. I don't mean Idle in the traditional sense of the word, I mean lawnmower idle, which would be full RPM. BUT that said, I replaced the carb today and the old one was missing an O ring that could have caused a vacuum leak, so that alone may fix the problem. It...

Because you don't have time to use a customers machine for a few weeks to let seafoam work its magic. But as a homeowner, I have that time. Also I'm not against cleaning a carb. Well, I am but not like that. Why bother cleaning when a new one is $10. But I'm just saying, it doesn't always fix...

I have to disagree on the effectiveness of seafoam. It doesn't always solve the problems but it has helped a lot more engines for me than it has done nothing for. Two mows isn't a very long treatment but because I need to sell this mower and finish it's video, I really don't have time to mow...

Ok update time. I removed the rod holding the back door in, and I removed the back door, then I removed the springs. Turns out, the springs are both in perfect condition! The problem seems to be that the door has a little hole in its plastic that the springs slide in to. And that hole has...

Ok I've now mowed my lawn twice with this mower, and its a pretty big yard for a small push machine like this. No change in sputtering/misfiring at all even with all the seafoam I ran through it. I even ran it dry then did a little more mowing with just clean, straight gas, incase I was...

The larger vice grips and the hammer worked. Very very slowly but i was able to get the rod to start moving.

Oh so turns out the "unformatted" number DOES find the engine on jack's, they just have an odd search result page that really makes it look like no results were found, when there actually is a result found! Also brand new carbs are $10 shipped on ebay LOL yeah I'll just get one of those.

Yeah so the choke opened slowly but it definitely did open fully. I have had a few engines over the years that ran rough, and with some seafoam treatment over the long term, they would clear up and run well again. But the plan is to get this thing running good and sell it. I don't have time to...

I poked around with this today, using vice grips. But the rod is pretty rusty. I was able to get it to rotate but I was not able to slide it at all. Any tips for how I might get it to move? My only idea is using a bigger set of vice grips (i was using a mini pair), clamp as hard as I can, and...

Ok this is weird. I did find another label that had the engine model and serial on it. But the format of the number does not seem to match the format the briggs & stratton website is looking for when you're trying to look up a motor! And I was not able to look it up on jack's either...

Update: Yesterday I fired it up, clamped the handle, and pulled the air filter off. No change. Also regarding the choke, first dumb question, is the choke the FIRST butterfly you see looking into the air intake from the air filter? If so, then it was opening up fully. It was moving slowly, I...

So I was able to find a TB110 diagram on jack's site, but it doesn't include the engine. Here is my engine label, it has lots of odd numbers on them but I can't seem to successfully search any of them to get an engine diagram. Did I miss a different label or is something else going on here? I'm...

With all that rust, thats not going to be fun. It looks like theres only an opening for it on one side. So is the idea, that you grab it with some needle nose in the middle and slowly inch it out bit by bit? Also regarding the rear flap, the "trailflap" (#4 in that diagram), do you have to...

Here is video of the machine in question. Funny thing is, on video it doesn't really sound like it's doing anything. But in person, its definitely running rough. You can see at the end of the video, how the handle is vibrating. Ok so the backstory. This is a trash rescue. It was overfilled...

Here is a closeup of the rear door and springs. They look pretty good. The springs look like they are installed right, they don't look damaged or corroded at all. Very weird. It's like the original owner left the bag on for 6 years straight and the springs just "unsprung". Also it's not...

Depending on how easy it is to get at the springs and remove that door, If they are too stiff to go around another loop, then they are probably stiff enough that I could bend them a little and make them tighter that way. Then again, new springs are pretty cheap it looks like so maybe I just...

Thats very strange that the flap would break so perfectly straight like that. I couldn't cut it that straight with anything but a table saw. Regarding the springs, you can get a good look at them wtth the door up, no rust or dirt or grass. The grass in the picture was from the minutes leading...

I have a couple of issues with this TB110 I'm trying to fix up. The first is the flap at the rear of the machine. Here is what mine looks like. It this correct? Every other mower i've ever used has had a much bigger, rubber flap that would push down on the lawn. I thought the purpose of these...

Yes I am aware this plug is unusually wet, which makes sense as the mower wouldn't start. This is the machine that turned out to be overfilled with oil. But I'm only making this post to ask, what is the condition of this plug itself, not the motor overall. Besides behind wet, this plug looks...

I'm wondering if maybe I didn't word my question clearly because you guys seem to be talking about totally different things.

What makes a mulching mower, a mulching mower? Is it just the style of blade? The blades with the fans on top to do extra shredding as the blade spins? If I had a mower that had a plane blade, can I make it a mulching mower simply by putting a mulching blade on it? I got a free mower I'm...

Ok this seems like a pointless question. But it's actually kind of important because I make yardwork videos and getting the spelling right could mean a lot more traffic. I've always spelled it "weed wacker", but technically if you're just going by the word definition, "whack" means to hit, and...

So what is the purpose of the engine brake? I only found out about this feature recently. It seems kind of pointless to me. Who cares if your motor takes a little longer to stop spinning? It seems like that would not effect me at all? Is there some benefit to this feature that I'm not missing...

Update: So I make yardwork related youtube videos. And I thought, oh here's a good opportunity to make a how-to video for changing the oil in these machines without making a mess. I thought I figured out the key, which was to put 4x6 scraps of wood under the right side wheels so the machine...

I pulled this mower out of the trash last summer. Physically it looked like it's in decent shape. And it has a bag. I tried to start it for the first time today. I'm not actually repairing it yet, I'll do that this summer. But I had it out so I figured let me give a few spins and see what...

Are you sure? Did you look at the timing? I don't see how an engine could possibly run with that valve timing. It's doing an intake stroke then immediately an exhaust stroke, THEN with no possible air and fuel, it's doing a combustion and then a compression stroke. How can that possibly be...

Did you look at the video of the valve movement? That can't possibly be the correct. I don't see how an engine could ever run with the valves opening and closing in that order.

Not that I would ever do this for a yard vacuum engine, but does anyone make an aftermarket aluminum camshaft for these engines? There are many USED plastic camshafts for this engine on ebay for like $10 shipped. Given that you only put like 5 hours per year on these machine, I'm thinking...

I never would have guessed that these engines had PLASTIC camshafts. So it again sounds fairly plausible that I overheated it and I guess just severely deformed the plastic camshaft. I'll have to take everything apart to get a closer look. The movement seems so smooth, that my guess is that the...

I looked in the parts manual for this machine and according to that, the engine is a B&S/Craftsman engine Model number 126T02 Also according to that manual, not only are my 4 cycles in the wronger order, but the engine is pulling in through the muffler and pushing out through the intake. Also...

I *am* turning it clockwise so I am spinning it the right way. What I'm seeing in my own video is an intake down stroke followed immediately by an exhaust up stroke which makes no sense. And then a full up stroke and down stroke with both valves closed. It's like one of the valves got knocked...

When I made the second video above, with the valve movement, I was only paying attention to the opening and closing of the valves. And they do seem to be opening and closing fully. But the more I look at that video, the more confused I become about the timing of the valve compared to the...

I just had a thought. Magnets loose their magnatism if they get hot. I don't know how hot. But could I have overheated the engine enough that I demagnetized the magnets on the flywheels so the motor can't generate spark anymore? I could feel some force from it for sure but I don't know how much...

OK I finally had time to work on this again. Here's how it went: I took all the covers off and there were a lot of maple tree seeds shammed in all over the place. No mud or slop or typical nest stuff, just maple tree seeds. Its unclear if it was enough to cause cooling issues (maybe? maybe...
