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...

I just happen to watch a video of an 18.5 horsepower OHV engine model 31 and the guys getting 125 psi. I can only say it seemed like none of the four adapters in the kit fit correctly into the spark plug hole. So I just ran the hose with the fitting and the gauge on the other end. I'm not sure...

I was hoping to upload an image of the compression tester gauge but the image is too large anyways, so it's a cold engine. I opened up the throttle choke and all that to get a lot of air in. I then came up with 75 lb PSI and I tried a few more times and it did not get any higher. I did not add...

Ironically I just watched that video again and it seems like the fellow is only paying attention to the intake valve and then he concluded because of that bump that the camshaft is okay and then he was able to put it back together and get it going

Yes Mark it is a single cylinder engine but one thing that I did find when looking at various videos and I think for just Briggs& Stratton engines is that with the valve cover off? If you look at the rocker arm where it makes contact, basically with a tap pet and the valve spring. In other...

Okay Mark I see what you mean. Yeah this is a mower deck.

Mark, I also reread the part about what you're talking about the blades and that's good to know. I think I'm just going to wait for the compression tester come if that's a simple test you are suggesting and maybe later tonight when it's cooler, I'll try that.

But to answer your other question, it's a sing le cylinder OHV intek engine 19 and 1/2 horsepower and I think it's called the gold edition.

I can't say that the motor mounts are loose but I'm not going to mess with those until I at least get basic rotation. That's what I'm thinking as far as the blade goes. I'll keep that in mind, but technically speaking, the blades should not rotate since the PTO is not engaged, but I'll reread...

Okay, thank you very much for that info. I think I'm going to start with your first suggestion about compression. I ordered a compression test kit and it should be available tomorrow and I suppose I could take off the flywheel today but I think I'd rather wait until the compression test is done...

The other thing I'm wondering about which I might have mentioned is I removed the flywheel and I replaced the key with a brand new key. It's the exact same key because the first one that was fine. I lost some place in the yard but I just wanted to throw that in just in case, despite what I...

The link I provided for that website that is exactly the engine. I have yet to go back outside and take a small picture of what is actually stamped on the riding mower itself. Also, I do have a smaller picture of what's on the valve cover but it's almost impossible to read and it might provide...

https://www.partswarehouse.com/31P677-3373-G2-Briggs-and-Stratton-Engine-s/235041.htm Thank you very much for your assessment. That makes a lot of sense, especially the part about. Well, if the spark is at the spark plug then you can just rest assure it has nothing to do with all that safety...

I apologize to everyone who has viewed these posts because all the information I provided kept changing from my perspective because I couldn't figure out what's going on. But here's what the whole thing comes down to and I'm pretty sure of this. I'm absolutely getting spark if the spark plug...

So here's where it's at as of 7:14 p.m. this is like day 15. I was able to flip the ignition coil upside down and produce spark in the spark plug tester and then removing the spark plug tester and starting the engine, it still will not start the flywheel spins there's popping in the intake of...

I did see this message. I'm having trouble resizing the image that I need to provide to you. Be back when I can figure it out Lt2 000. Model number 917. 28970 this is the best I can do right now

The problem is, for whatever reason the engine does not turn over and I thought I had good spark from the spark plug. So then I'm thinking if that's the case then something to do with the carburetor or then I was thinking somehow the kill switch is doing something to prevent the engine from...

I was hoping to delete this post but I have no clue how to. In any case, I just bought a spark plug tester and I'm not positive if I'm getting spark to the plug. However, testing in a different way shows there's spark to the spark plug, so I got to figure this out is a spark plug getting spark...

In the last two weeks I've done many things, but in the meantime the current problem is this definitely getting spark to the spark plug after spraying carburetor cleaner into the intake while turning the key. The only thing that happens is backfire through the carburetor or popping the engine...

Hi, I have a 14.5HP Briggs engine and was able to get it running right, very smooth. As of today when turning the key their is a loud banging noise and then it runs fine. So now every time you start the engine their is a loud clanging noise and it goes way after the engine runs for maybe a...

Hello, I decided to start a new thread to try to figure out if a problem with my tractor is electrical. Tell me if these steps make sense. 1. Remove the ground wire from the coil. 2. Start the engine ( turn the key ) 3. See how well the engine runs. Does it cut out? I guess what I don't...

Hi, I have an older MTD with a 14.5 HP Briggs engine. I had it at a shop for about 3 weeks. The mechanic replaced the fuel line, the spark plug, the fuel filter and the air cleaner. I brought it to him because the engine kept quitting. So he delivered it back to me today. The driver drove it...

B&S 14.5 HP engine cuts out after 10 minutes Hi, I have a B&S ( 14.5 HP ) engine which had a carb rebuild last year and ran great. The tractor sat outside over the winter. And so far I have cut the lawn 3 times this year without a problem. Yesterday the engine just started to sputter ( after I...
