I think I forgot the spring from the governor arm to the control plate to pull the throttle cable. Now that I put it on, the governor surges and the idle will not smooth out. I have a shop manual, it's confusing to me. I'll have to reread and review what I have.

This control panel and linkage is difficult to do correctly if you're new to it. I'm in over my head. It seemed simple when I took it off to clean the carburetor. Now I don't have throttle control. Something is wrong here.

As the owner, that is what I'm trying to figure out. I wanted to clean up the cylinder walls prior to moving on. I've replaced the carb, same problem continues

300 hours, compression 110 to 120 cylinder 1 and 2. Only white smoke Just want to make sure I understand prior to reassembling.

That is good info! Some one has been around the block a few times. Stuff the average person wouldn't think about. Thanks

Is dark areas caused only by heat? I saw the dark spot and light scratches and thought it was ring damage!? I don't understand all the clues and hints as to what it's telling me.

I pulled the engine it's on my work bench now. That was what started the post. I had seen other posts about blue loctite and I had never used it before, so I was asking if I needed it and was wondering if the head bolts could be re-used. I see that is just fine and no blue loctite. Now I...

I ran scotchbrite around the top 1/4 inch. Only 315 hours on the machine! Some of the guys recommended decarbing the pistons at 300 hours. It had started blowing white smoke when I started it. After the first cut of the season it was smoking (white) full time. I was new to engines so I pulled...

Thank you, great help

I bought it new Husqvarna ts348xd with a Kawasaki fr730v. All tin and all air flow covers are in place. Never ran stripped down. Was very clean until this winter, I found a mouse nest under the covers but no run time on it.

Thanks, marking the piston is a good idea. Does a wrist pin extend that far! I have to check that out!

Any idea why the dark area formed and what may be causing the start of scratching? I was thinking something in the rings dragging up and down to cause the scratching.? But why the dark area, heat?

You can't see the light scratches just above the dark spot. You can't feel them but they are just starting to scratch the cylinder wall. Very light, no depth yet. I was hoping they would show up. I'll get some sizes in the next day or so. Looking for my i.d. micrometers and telescoping Gauges to...

After pulling cylinder head number 2 this is what I found!! I was shocked to find this with only 315 hours on the machine! What is this telling me? I pulled the engine and I have it on a work bench. I didn't open it up yet. Ordering rings and crank seals, should I also order seals for the governor?

Thank you

I'm at 300 hours and took the heads off to clean the carbon from the pistons and check the valves. Should I replace the head bolts or re-use the original bolts? Where should I use Loctite, I was told that the blue loctite needed a primer when steel bolts go into aluminum?

Big update When this problem started , I had white smoke when starting cold with a choke Thing have changed in the last couple days!! Now smoking non stop. Surging, still getting gas in oil. Well I pulled the spark plugs and put the bore scope back in Now I'm seeing vertical scratching Forming...

Good idea thanks

The other day, I rechecked my valves. I have them around .004 If I can see them to get to top dead center of my stroke then they aren't hanging up, right? The valves are moving and good gap. Good compression around 100 to 105 psi. Can I still have a gasket issue? Don't get me wrong , I'm very...

I don't know what to say, my first time using it I'm just trying to understand why it's sucking so much gas, and why is it wanting to run with such a high rpm. I have what I think is good compression. 100 to maybe around 105 psi on each cylinder. Does that tell me my rings and head gasket are...

Thank you, this clears up some confusion. I did a compression test the other day and cylinder 1 is 100 psi and cylinder 2 is just over 100 maybe 105 psi. I forget what the plugs looked like, I'll recheck that today.

Was just messing with it, and it kind of holds the throttle near half throttle or greater. Then it moves and surges,and goes back to mid throttle or higher

I picked up a new carb, and pressure tested both new and old, they pop off at 16 to 17 psi. Cheap gauge, it could measure off a little. If I didn't need to cut my grass, this would be interesting, sure has me on YouTube every night

Sure does, I forgot to say that in my post. Had to replace the oil, twice in the last two weeks! What is sucking that much gas? It's set up for gravity feed and disconnected the governor , so I could control the idle. Most of the time, it runs fast even when the throttle is turned down all the...

I have a Husqvarna riding mower. Posted as white smoke when cold start. History I chased my tail for a couple weeks. Ended up getting a new carb and a new fuel pump. Still the same problem but now white smoke is constant!! New effort. I set up a gravity feed fuel line and removed the governor...

I'm tempted to buy a new walbro carb, but what if it isn't the problem. I can't just throw money at it.

This morning I ran a pressure test on the carb, held 15 pounds for an hour and never moved, perfect!! Then I installed it and it still surges, so I removed the springs and linkage to the carb and ran it with no choke and no throttle. I control throttle by hand. Runs steady but will blow out...

I just ordered a pressure tester gauge On the walbro LMF K12 carburetor, it's hard to set the float. I don't see info on setting it, only thing they say is check for level. When the throttle lever fails to work right, that is confusing. That is why I thought it had a vacuum leak in the gaskets...

Slomo I've had this carb on and off several times, looking to see if the throttle issue might have been from a vacuum leak sucking air in the line. At first it took me a couple hours of bending over in a poorly lit garage at 25 degrees. I'm understand much better now what everyone was telling...

Slomo I did watch the videos. And saw they were testing 2 cycle carbs. I,also saw where the one gentleman made his own. I just don't have the stuff to make my own. I'm just getting started, its all new to me. On a fixed income these gages and other tools take a little time to acquire, I simply...

Starting to understand small engine carburetors to a degree. Looking behind the control plate, and understanding what I was looking at took a little getting use to. The first time I took the carb off, I dropped the choke return spring when re-assembling. I now understand the throttle link and...

I ordered a fiber optic scope to look inside, it should be in early this week. I'm hoping the cylinders are okay. Part of my problem now is me! I now need to review the throttle return linkage. I move my throttle control lever and the carb doesn't respond. It gradually starts racing and surging...

I saw the 2 stroke on line, it seemed to be the bigger focus. I didn't see the 4 stroke videos, thanks. I just picked up a tac meter, and should be seeing a digital scope to look inside the cylinders. I just took apart the carb again. The main nozzle and jet was so clean looked new, no dirt in...

Surging

The choke and throttle move smooth and are showing no signed of sticking or dirt

I'm trying to attach the video, only a few seconds but it's to big! Darn

After you finish laughing, can someone give me a direction as to where to start!! This is my first carb clean on a larger carb. I have cleaned a simple small carb and it ran okay, I was just lucky. Sorry can't get the video loaded. I'm now having surging. I pulled the spark plugs, one is dry...

I like the reminders I find on many of the replies I see on the forum Example Have you ever pulled the metal engine shroud and cleaned the top of the block and cooling fins? This is a yearly maintenance item in ALL engine manuals. Neglect this and you are looking at engine damage I think you...

To my surprise, it is now 5 years old this month. I cleaned the engine, and I checked the valves. Question Kawasaki service manual shows the valve settings for .002 to .0039!! Googled it and most internet info shows it .004 to .006 I'm setting them To .004 if I can tighten it and keep the...

Now, can I get it all back together, and have it all run good again As scary as this is for me, it is also rewarding to learn and accomplish it.

Between a dirty air filter and a mouse house under the cover, wow I could have over heated the engine and dropped a valve!!! Forums are very helpful I'm very thankful for all the good advice

I found a shut off down under the battery area, I never would have known about it, until I took the cover off the engine. It was so well hidden.!!

Thanks, great advice Will do

I just talked with a mechanic, he asked about my air filter!! And explained, if blocked, it still wants to move air flow and if there is no air it pulls more gas!! I just did a lot of earth moving this past year, putting in drainage pipes. I had a lot of dust, and never thought about it. I'm...

Only white smoke and only when the choke is on.

Smoke is white, I also noticed when doing my spring oil change, I'm getting gas into my oil! I picked up an ultra sonic cleaner after reading more on this forum and I've pulled the carb to clean it. I'm picking up a new float valve today, along with gaskets and o-ring for the bowl. I hope I can...

It doesn't start with out choking for a few seconds. The first couple years of use it had no smoke when starting. The smoke alarmed me and I was just trying to understand why it was now smoking.

Spring mower tune up Two riding mowers, both smoke when cold and using the choke! Smoke stops when the choke is off. I use ethanol free gas. YTH1542XP with a Kawasaki FH430V 954568465 Husqvarna TS348XD (48") 24HP Kawasaki FR730V CODE: FR730V-GS04-R E/NO: FR730VE37822 S/N: L2009140331
