So I use some of that high temperature red sealant and I locked down the valve cover but yet there's oil dripping directly below the valve cover and I can't figure out where it's coming from. Meaning maybe the cylinder head? Maybe the block itself? J8m

I try to adjust the carburetor while it's running with that that engine housing on and I couldn't do it but with the engine housing off it's doing the hunting and surging thing again and it sounds like it might even be banging. It just doesn't sound right. And the throttle. So the throttle...

Okay got it on those issues I did read if you run it too. Lean it gets too hot so I'm going to fix that a little at a time. When I had the flywheel off I was going to inspect that breather assembly but that didn't happen. Hoping whatever hunting and surging is going on is 100% carburetor that I...

What I'm trying to say is it's better to have one person telling you or a couple then reading a million different articles. That's what I'm trying to say because it turns out to be a million different things

So I just was reading many articles on running hot and obviously was not a single person telling you you have a million different things. But I'm wondering first of all it could be running too lean and then the air filter. There is none right now so maybe the breather tube? And I wonder about...

So the temperature of the exhaust pipe is about 800° f and the plastic fins are broken and I did not put the the shroud around the engine but I'm not exactly making it work hard. It's just sitting there running. It is starting to exhibit the hunting and surging issue from say 2 weeks ago and...

Lower left corner of the valve cover has some oil dripping. The valve cover is not a perfect seal but could there be something else going on?

ILengine thanks for your help on this so far it's the success if I have a damaged flywheel fan and I certainly don't want to screw off anything that I spent about 16 days trying to fix, but I'm wondering if it can cut? Say maybe 800 square feet without blowing up. Definitely got to order...

So I tightened it up to about 100 foot pounds. And then it wouldn't restart. I thought shared the flywheel key again but I decided at that point even after torquing it to torque it a little bit more. It's pretty much up near 100. It's an old school torque device

It runs it skips here and there no more banging noise. Maybe a slight hunt and surge. I have not adjusted the fuel air mixture screw nor the idle screw. Jim

ILengine thanks for your help and all this. I can say it's pretty wet outside and tomorrow morning I'm going to be trying and get everything going. But the only other question is, do you recall a stand-alone washer that sits on top in some order before the actual bolt? I do see how the bolt that...

Thanks IEngine

You know I vaguely remember that from 3 years ago. I'm going to go back to that spec. Apparently 80 ft lb is incorrect. I also figured out my flywheel is tapered and from this other website entirely the guys saying it's mostly for positioning for the initial installation and he said you could...

Mark Mark, yes, as far as the blade, I don't think that's an issue at all because the PTO clutches off, but I could freely spend the blades just to make sure there's nothing going on down there. But generally speaking, they're not an issue unless you decide to engage the PTO clutch, but I will...

And of course I find this. After I make posts to this forum. I got to figure out which one I have.

I found this in another form and I'm pretty sure the issue about taper applies to this engine completely. So having said that, I'm wondering if I just use the flywheel keys that I bought already rather than buying the specific model number that Briggs and Stratton recommends. This is kind of...

I didn't see your reply the first time around and I see what you're saying and I'll have to reread it. But what are your thoughts about using in theory the correct length? But according to Briggs& Stratton I bought three of the wrong kind even though they're a half inch long? Thanks, Jim

796335 Is what I should have ordered. I think it's the original Briggs& Stratton part. This one is listed as a 1/2 in Long and maybe I need to order that one. I have no clue if the other two I have which are not the right model is why it's sheered a few days ago

Briggs& Stratton 5002k Is what I ordered about a week ago and the only thing I could say is they're about a half inch long. Your choices are a half inch long or I think 1 in long. So the one I had for 3 years and it's probably still good but I can't find it is one half inch long so I got the...

So obviously the flywheel key is sheered so there has to be reasons for that and it probably happened the very first time a few days ago after I put the flywheel back so it probably broke pretty quickly. So there has to be a reason for that. I'm going to say one reason might be I didn't torque...

Oh I think I see what you did. You measured the amount of movement the difference and you came up with 1 cm where I was giving absolute coordinates more or less. So yes they both travel about 1 cm just like yours travels about 1 cm. I think that's what you're saying now. I misread it

Actually before I do that so I mentioned above that when The rod for the intake travels back inside the engine. The distance to that plate is 2 cm. It only goes in as far as 2 cm. You're telling me yours travel s in to the 1 CM Mark. Where is mine does not. Do you think that's a problem? Jim

IL engine thanks so much. So I haven't taken off the flywheel. But like I said I'm not a mechanic and I don't spend a lot of time with this us. Although over the course of say 50 years I have spent a lot of time on this but the only thing left is in your opinion and for now is it take off the...

I was able to crop the image and this would be the intake valve and it might be hard to see the number 3 cm but you can clearly see 4 cm. So that's how far away from the cylinder Head that the rocker arm travels so like I said it travels 3 cm away from the engine as measured from the flat plate...

I'm not sure if this is always a rule but I believe when the Piston is at top dead center The rocker arms are exactly the same distance from the cylinder head plate and then it seems like the intake valve has a rocker arm that pushes the Piston rod out a little further than on the exhaust valve

I don't know what happened to my last post but I can absolutely say the intake valve which is the bottom one. The maximum travel of the rocker arm tap that intersection is exactly 3 cm

I got to go back outside. I know the bottom one is the intake and the upper one is the exhaust. I just got to make sure that I didn't switch the labeling. The dimensions are correct. I just don't know if I made a mistake with the labels

Intake valve. The maximum travel out is 3 cm rocker arm Intake valve travel comes up to 2 cm. Mark Exhaust valve when it goes inside. It's at the 1. 2 CM Mark Exhaust valve all the way out. It's at the 2.3 cm. Mark Okay these are just raw notes. The way I'm measuring is I go to the...

I failed to mention I couldn't be bothered putting the valve cover back on because I knew it wouldn't start but I would never run it in a well-running engine with a valve cover off. It's just been constant going back and forth. So the only thing that I was wondering is if the folks here believe...

So the ignition coil has a pretty good air gap. Nothing wrong with it. The spark plug is in all the way and the boot is secured onto the spark plug. The first time I sprayed carburetor cleaner the throttle was not right so I opened up the throttle went to high speed choke whatever and then I...

Ilengine, Okay it's early here but the first thing I'm going to do is basically show the state of the system in a video. So when I get outside it'll be simply a video of the flywheel turning and no start. And that's right after carburetor cleaner. Just sprayed in but I have been thinking about...

So I've been reading about some of the symptoms of a cracked cylinder wall and they mention white smoke coming from the exhaust that has happened. Say we could go. Also the the exhaust pipe was reading about 850° f after say 20 or 30 seconds I replaced the head gasket but the strange thing is if...

I see a lot of information here and I appreciate it. I will check all this out tomorrow.

Mark, I'm sorry I am not going back out. I should have mentioned that I'm going to start on that tomorrow, but since you brought it up I wonder because I don't use a flywheel puller and I had like a metal bar underneath the flywheel while I was tightening it if I broke something underneath the...

This is what I bought on June 26th

So I have three brand new plugs and maybe I only swapped out two of them back and forth. They all light up, maybe even the third one but I haven't actually tested that one. It's still in the box it it meaning the spark plug tester looks like it has some metal coils inside a clear test tube and...

The only thing I mentioned that I failed to mention is maybe 10 days ago the fan that sits on top of the flywheel which is a piece of plastic. Basically those fins started breaking off and I thought that was strange but that must indicate something. It was in a test environment. Let's say no...

So as far as the spark plug goes, I have a spark plug tester. So if I test a spark plug and I see the light inside the spark plug tester, I'm assuming that the spark plug's okay and so that is done but maybe not. Maybe there's some weird thing going on that I can't figure out. Okay, as far as...

I just read in some other form. This sounds kind of like what's going on with my riding mower. https://www.doityourself.com/forum/outdoor-gasoline-electric-powered-equipment-small-engines/352247-briggs-stratton-wont-start-but-has-spark.html Except he finds out there's a bent push rod or a...

Okay definitely the motor mounts need to be fixed but suppose I have a dead engine I would think. And I'm not a mechanic that if you have compression you you passed that hurdle. If the push rods are okay, you pass that hurdle. If the rocker arms are okay that's good. I'm trying to figure out...

And I should point out before the constant banging. This engine was unbelievable. This thing could fly around the yard. It was an amazing machine and then it just broke.

Mark Mark, it's been tough to follow all that is happening two or 3 weeks but it went from starting up instantly but with a constant banging noise to the flywheel turning perfectly but no start even with starting fluid which has never happened before with this engine and that's where it's at. So...

So I use the compression tester one more time. I found out that none of those adapters fit into the spark plug hole but they supplied basically a pipe with like a cone-shaped rubber boot on the end and I use that and as it turns out I got up to about 85 psi. I most likely bought junk where it...
