I removed the kill wire. It was still hunting and surging and as I recall years ago I got rid of the electronic solenoid and install the shut-off switch for the fuel line. But in any case, although you don't see it, this is a video where it's running for a few minutes. It's hunting and surging...

Thanks for this. You did not waste words I will be checking this out. Jim

I have never heard of a magnetic dial indicator. I will look that up later and its usage. But one thing I was messing around with few weeks ago is trying to figure out if some of the safety features were screwing up the engine and then since I had constant spark I thought no issue with the...

https://www.partswarehouse.com/31P677-3373-G2-Briggs-and-Stratton-Engine-s/235041.htm I have been using the above website link for the engine and this goes back like 3 years or more. I also considered trying to use steel wool on the parts I couldn't read and then I was thinking maybe I just...

I started to take a look at what you wrote and I absolutely will remove the kill wire because right now it starts right up it hunts and surges and the temperature gets up to about 800° f ine. I didn't know at the time what the purpose of removing the kill wire was, but now I know and I can...

It's late at night, but it seems like you have a pretty exhaustive list of things to look at. And I absolutely will read it tomorrow morning. But I've included the engine code and it's just so hard to read and I'm pretty sure this is the best photo which is cropped that I have Jim made

But the weird thing is maybe 5 days ago it was running very smooth. Everything seems smooth and the engine temperature was about 450° Fahrenheit. Maybe 500° and then something happened then and then it went back up to 800° f

I actually was thinking this just about the fan that even if I get all the fins I'm still going to end up with around 700° f. But like you're saying regarding the governor, since the component is inside and I'm not an engine expert wouldn't I would not know this if this is broken or not. If...

I see what you're saying and that was definitely a mistake on my part as far as describing the problem. But the fact is the flywheel was rotating and nothing else was happening. And at the time the reason why that was true is because of flywheel key was sheered and that was fixed and as of July...

I actually did this maybe 5 days ago and I came up with a distance of travel of 1 cm approximately for each valve and another member of this forum computed the same thing for his machine. If the 1 cm difference seems wrong then I have the units right here in my description wrong. But whatever I...

I absolutely can do this tomorrow just to at least make sure the valve clearances are correct. The push rods are not bent. The post that the rocker arms sit on are solid against the plate and anything else that I find that might be unusual, but that's a good suggestion. Jim

Hello I bought a compression testing kit and although one of the fittings did not fit perfectly with a spark plug hole, there is an adapter that makes a pretty good fit and the compression was 86 psi. I stopped using the carburetor cleaner. The only reason I mainly did that is so I wouldn't...

This is from 5:15 p.m. July 6th so the engine starts. Right up and at least I guess I only contend with one variable now hunting and surging. It sounds like the carburetor so I put the fuel mixer screw in all the way and then I backed it out about one turn and every 30 minutes or so I back it...

Right on that. The part I'm looking at off the top of my head is Briggs& Stratton 796201. I think that's what it is I lost the post but someone was telling me about the flywheel fan and I could say the part that I need is Briggs& Stratton 796201 and that's everything but I only need the plastic...

I just went back outside at 3:15 p.m. I am keeping in mind running this even with everything back in place for under say 20 seconds. I can say it started right up. It sounds like the engine's strong and a lot of hunting and surging. So in a couple seconds that I had, I started messing around...

Forest, I did take a look at that flywheel fan. I was looking for some numbers or letters and there is nothing except the Briggs& Stratton logo put. The one I have has two dimples on the bottom and I can buy like three parts and be sure I got the correct plastic fan but I am trying to figure out...

Forest, thanks for the heads up on this. Even with everything put back in a partially broken flywheel fan which recently broke and I have no clue why. But the point is what you're saying makes a lot of sense about the fan and go to a place that has old engines before anything else. I do...

I have to put the original coil back on and this is a good point you make. Honestly, I don't think it'll make any difference but I absolutely will put the old coil back on.

It starts up perfectly fine without carburetor cleaner is what I was trying to say

I am sorry I was using carburetor cleaner. I can tell you that the most recent startup was without carburetor cleaner because everything was put back on the engine including the housing and it can't start without carburetor cleaner. I just wanted to make it easier for whatever is going on with...

Honestly, I've watched many videos on adjusting the valves and since I've spent so much time with this, the technique I like to use is where you send one push rod into the engine as far as it can go and watch that rocker arm. And when you know it's pretty much as far as it can go. You adjust the...

Thanks for this message. I can put the the original ignition coil back on there. Probably wasn't anything wrong with it. I just figured it wouldn't be a bad idea to replace it. Actually a couple strands of wire were frayed up near the electronics of the ignition coil. That's why I replaced it in...

Okay, thanks for the tip on that. You know obviously comes down to 2200 bucks versus will a couple hundred dollars say $300 total? Will that? This is the way I'm proceeding. I can only tell you about 10 years ago I had a Briggs& Stratton with a cracked cylinder wall. I used JB weld on it and it...

Okay this is a video with everything back I did not engage the blades. It started to do some hunting and surging and the engine runs about 770° f so it still doesn't seem right. I could take it out. Cut a little bit of grass and then it just shuts down. Maybe I got to do that. I think that would...

When you say stator key, do you mean flywheel key? I know that right now has been torquing down to 100 ft lb and I just made a video of it running bare Bones, no blades running, no housing on the engine. Just does it run and so far it runs without any blades turning and I'm not sure for how long...

I got the flywheel to 100 ft lb. I put everything back. I noticed there might be a problem with the threading for the spark plug hole but I found a spot where it actually can tighten okay but any further it would go back into being loose. But having said that the link above is the machine...

I'm sorry for the confusion on this. There was no intention to ever run the flywheel without a flywheel key. I was talking about what the purpose of it is. I would never run a flywheel without a flywheel key

And there's just so many different things to remember, but one thing that I noticed only a couple days ago. 800° F. Using a thermal gun so there's something wrong with the temperature on the exhaust so I got to look at that too and I think that's everything before I go outside and get the...

Okay to answer your question, 3 weeks ago there was a lot of smoke coming from the exhaust. I thought it was the cylinder head gasket and it may have been in reality the valve cover gasket. I failed to follow up with what happened next. So what happened next was I put oil back in the engine but...

Kyledere thanks for the reply. I can tell you about 3 weeks ago there was smoke on the muffler and it was very smoky and I thought the problem was a head gasket. I really didn't know what the problem was but at that time it had awesome power. There was nothing wrong with it except a lot of smoke...

It's July 6th 2024 and I can see where I have posted some years ago about a problem with the Briggs& Stratton engine and somehow I think I'm replying to a problem from back then. I can't figure out what's going on with the forum but from here on out I'm going to post the date and the time in the...

Thanks for your reply on this and I can only say I swapped out the original carburetor I put a brand new carburetor in which actually if you know what you're doing only takes under 5 minutes or less and it was the same problem. But having said that, since I went back to the original carburetor I...

Thanks old and tired. So I just did a search on symptoms of a bad timing gear on a crankshaft for Briggs& Stratton engine or something very similar as a phrase. And again, I'm not an engine mechanic and I could tell you there is no way in hell I could ever come up with that phrase with what I...

Correction. I was not able to get it off last night. It was impossible to get it off last night every time I turned I can only say this forum Is great and what I know is many of you. If you are standing right over this engine while it was running, you could probably figure it out instantly. I...

Correction. I was not able to get it off last night. It was impossible to get it off last night every time I turned those nuts. Clockwise I expected something to break free and that never happened. That is what I was trying to say above. So at that point I couldn't figure out what was going on...

I was able to remove the flywheel. I have no idea where the post I just made ended up including pictures of flywheel keys. But the only question is about the notch cut into the flywheel key and the only reason I could see it being there in the first place is you can probably grab it and then...

In other words, when you see the notch point it towards the sky?

I went outside to start over. I backed out the bolts and as I did the flywheel was loose. I was able to get it off when I was tightening down last night. There was no indication that I was doing anything productive, but the key towards the bottom of the screen has some damage from when I was...

I'm hoping this is the problem. The first step should be tighten the bolt all the way down through the flywheel so that the end of the bolt makes contact with the short block. Otherwise it will not work. But if that is the problem then I'm thinking that's a lot of force confined to a small...

So I turned each nut probably 50 times and nothing is happening. I thought the flywheel was supposed to break free from the crankshaft. Is this a common problem where this tool does not work? Jim

Just to be clear, I bought all kinds of new components. I would swap the new one in. I swapped the old one out. I swapped the old one back in. I swapped the new one in. It doesn't matter like all the old components are fine from what I gather

Hello Forest, I'm waiting right now as we speak for a flywheel puller because I can't get the flywheel off and I'm not going to try and pry it anymore. So before I decide to take the flywheel off, the engine starts right up. That's not even an issue and then it starts going into loud explosions...

For what it's worth, Sears has a video on replacing the flywheel key and in it they say push it down flush with the top of the crankshaft. I believe a few days ago I actually did that but I'm not positive but if I did then I don't understand how the flywheel key could have raised itself up...

Thank you very much for the answer Ilengine. Jim

I think what I failed to say is there's no way the flywheel key should be sitting up higher The other thing I noticed is if you rotate the flywheel so the magnet is directly on center with the ignition coil. I would think the notch in the crank shaft would point in that direction. It's not it's...

I think what I failed to say is there's no way the flywheel key should be sitting up higher than the actual crankshaft. I'm just wondering if that makes sense. It's not easy to find that kind of information only over hundreds of articles?

"Place the flywheel on the crankshaft and look through the flywheel hub to align the keyways on the flywheel and crankshaft. With the flywheel in place, place the key in the keyway; it should fit securely. If you feel play, check to see if the key is upside down."...

I have a flywheel puller made by Briggs& Stratton on order Is what I was trying to say above
