Just so there's no confusion for a very long time. It was starting up instantly and then all kinds of help broke loose when the last 4 days it struggled to start but then I found a bent push rod. Now all that's been cleaned up. So now it's starting up instantly and it's shutting down. That's a...

Forest, here's where that 19.5 Briggs& Stratton OHV engine stands so I put a brand new push rod. I happen to have an aluminum one and that's exactly what I needed and it was brand new so that's in place. The valve caps are in place. The intake is at 4000. The exhaust is at 7,000 brand new spark...

Omg I found this. I'm not saying another word

So with both valve caps basically the engine is destroyed. So absolutely time for the shop and not mine

And this is for the guy who thinks I'm messing with people. This is what happens. I'm not trying to do this. I want a lawn mower that works. That's all I want

What? I don't know is if you're missing one of those valve capsAnd and start the engine what will happen?

Forest it absolutely is in this little container that I saved. It has a bunch of flywheel, keys and all that other stuff. If you're betting on a fell into the engine, you're betting on the fact that I have 100% concentration and that's a bad bet so I have no idea. I'm just telling you what I...

So I don't know the significance of this but the Valve cap from the exhaust valve is missing. So I have to put another extra one on that I have and then when it doesn't start then I agree with you 100%. But I can't leave it like it is. The valve cap is looks like a little hockey puck made out of...

Actually the more I think of it. I want to walk back this this comment and here's why it might have been like a week ago I had the engine housing off. The engine started up right away and there was no hunting and surging. Maybe only a very little bit and I thought that the solution was something...

But having said all that maybe 4 weeks ago, some folks and I can't remember who they are said it's probably the camshaft. Maybe it's spent. Maybe there's something wrong with it, so if it was them they probably would have just proceeded to take take the engine apart but I didn't know if they're...

Forest, keep in mind I spent maybe 5 weeks trying to figure out. Is it something broken inside or is there something that's not adjusted properly? You know had I known 5 weeks ago, I want to bother messing with it on the outside and I don't have a skills to hear things that are going on inside...

I don't know if Davis I'm looking it this way. Well actually maybe you're right because basically the fear I have not knowing what the hell's inside that black box is it's going to cost like 10,000 bucks to have it fixed. The camera would at least maybe not increase sales straight away but the...

So maybe about 4 days ago I came up with the idea of putting a little plate on the back of the engine where you could look inside and I've since revised that it would be basically maybe an inch, maybe a half inch hole drilled into the back of the engine block and then from there you would just...

I could actually do that but I have to take the engine out and bring it to the place which I could do. Otherwise around here it's like 120 bucks round trip just to bring the whole riding mower. Where I live to very reputable shops are no longer in business due to various circumstances. There are...

I just wish there was a way to determine broken camshaft or say bad carburetor where at least one symptom does not overlap and then from there you can conclude it's one or the other. And honestly I'm not sure if I quit. I think I'm going to take a break from it and someone on this forum wants me...

The 19.5 horsepower lt2000 I think has a serious camshaft issue. Someone mentioned it before. I can't remember who but that very well could be true. I'm going with that now that I said this. It'll probably start up perfectly and cut through anything. But I have a yard machine. 17.5 horsepower...

A few days ago I tightened the four bolts and those things were secure, but I think you're referring to what I was trying to turn over the edge in. In other words, a flywheel rotating. It was like the whole chassis was shaking the wheels. The chassis that's what it looked like and I don't know...

It's signed up for the School of hard knocks.

I should say when there is banging. Probably the explosions. There were many many of them. This was one single bang and then the engine quit and I thought it was metal on metal but I'm not sure any more than that but it was just one bang as if something hit something and then stopped

Forest if this is in response to what I was saying about being 180° out of sync I think it has to do with after I set up the mark mark on the plastic fins with a mark on the ignition coil. I took the plastic fins off and when I put them back they can either go one way or the other and I think I...

I have never seen the outside of the spark plug boot with metal. I just wonder if this will screw up the timing or something similar and I should coat this somehow with rubber? Jim

Please ignore this because it's possible that I put that plastic piece on reversed yesterday and that explains it

I made those two marks 3 or 4 days ago is what I'm saying and that means top dead center but somehow it's 180° reversed so that Mark when they line up is now when the Piston is all the way inside the cylinder wall

So around 6:00 p.m. July 12th today. I tried to start the engine and it didn't sound good at all. Like something seriously is broken. I took the spark plug out and this image above. I specifically lined up the ignition coil with a flywheel. I made a mark on both and that means basically top dead...

For the above video, at the very end there was something metal hitting something else metal inside the engine that caused a bang. It was not combustion related that's for sure. So the first time I attempted to start the engine until July 12th in the morning I did make some mistakes with some...

Okay, before this video was made I made sure the spark plug was okay. It is. I made sure the rocker arms the pushrods that whole area is okay and it is. I unscrewed the fuel solenoid from the carburetor. Let the gas pour out. Put it back in and then spray carburetor cleaner into the carburetor...

The second video and I'm trying to keep track of everything that happens has never been seen before. It's all new and it's consistent with what I've been saying where whatever's going on. It changes everyday and I can't keep track of all of it. But unless it's a flywheel key that has happened...

This is the first attempt on July 12th around 9:30 a.m. and everything looked okay. Pre-flight except I forgot to turn on the fuel line and then I couldn't turn it off so I had to rip the fuel line out of the carburetor. I think the fuel switch works, but it would have taken too long. The...

It seems as if when you place the tractor on a level surface and you drain the oil and you remove the oil filter, you assume that there's no more oil because you drained it all and I'm not sure why he ended up with maybe a quart extra that I don't know. That is something that could easily be...

But putting aside the current current problem entirely and I'm going back to 3 or 4 years ago. When I got this machine the owner overfilled it with oil and how did that happen? And my conclusion 3 or 4 years ago was there's something wrong with a specification sheet or somehow when you drain oil...

Toby, thanks for the input and now that I'm totally more awake, you know I agree with what you're saying. Something goes wrong with the engine. Consider that one variable and then you still have that one variable. But now you introduce another variable some other carburetor. Now you got two...

Let me cut to the chase with this as to what I'm really saying. Maybe the one that's been in place for 3 years is just all messed up and the one I bought on Amazon say 10 days ago. It's just garbage and I thought they were essentially the same test but maybe they're not the same test. And I...

Toby, when I got this engine the entire machine should I say it was destroyed? So 3 years ago I purchased a brand new carburetor on Amazon. That carburetor has been awesome for the last 3 years. But I will admit the problem is I can't figure out which one it is that I ordered back then. Also, I...

Toby, thanks for this reply. A few weeks ago I bought a brand new carburetor for it and what had happened was when I began using the brand new carburetor nothing changed. So for whatever reason the carburetor that was running the best was the older one so that is still inside the engine. Now...

I'm going to add some text just to be clear. So essentially 3 days ago I was at the stage where the engine started up instantly and then it went into its hunting and surging. That is the last set of symptoms and then what happened because I destroyed the spark plug hole. Is the spark plug flew...

Hi Toby, I did see this on Wednesday. I got the cylinder head back with essentially a brand new spark plug hole, but I haven't done anything further except without a highly specialized test. I disconnected the quarter inch fuel line from the carburetor and I do have a shut-off valve so after...

Okay Toby I did read this. I haven't gone over your first post. You did mention about the camshaft so basically the removal of the camshaft. So in the past 6 weeks I have seen fire coming out of the intake. I have seen smoke coming out of the intake but not testing everyday. It's random...

So I thought about what I just wrote and I have a better question is if you see where the rocker arm makes contact with a push rod and that bump definitely occurs. What can you conclude about the internal components of the engine? Can you say well if you have the bump then that means this is...

Hi Toby, somehow I missed this. I just found it in my email a little while ago and I will read it. I mean it's pretty exhaustive and I'm sure it's complete. The one question I have for you and this got back to the crankshaft or the cam shaft possibly being bent or damaged and I think it was a...

Let me provide more context. So this is the very old cylinder head from a 14.5 horsepower Briggs& Stratton engine. The screw holes did align perfectly with a 19.5 horsepower Briggs engine, but maybe there's something different because obviously there is very little compression. The original...

Forest good call 35 PSI

Compression tester. I own that Leak down tester. I do not own that

I am sorry I have a compression tester when I don't have is called the leak down tester which is different. But you think I should test for compression because the compression tester I just bought I own that

Just to be clear, the awful banging went away say a couple days ago and I can't explain why. Maybe it had to do with carburetor cleaner. It is just very confusing and the symptoms change seemingly on a daily basis and I'm trying to figure all that out

I'm trying to determine say without using a leak down test apparatus. What's going on internally with the engine so right now on July 9th around 7:15 a.m. at some point soon I plan figure out why the flywheel keeps rotating. The spark plug does have spark but the engine does not start. The...

So many things have changed every single day. I can say right now 2 days ago there was no banging. There was just hunting and surging and then I blew out the spark plug. So I swap the cylinder head for a 14.5 horsepower. Briggs cylinder head and now the current problem is I turn the ignition...

The flywheel key looks intact but that means nothing. I'm wondering if I should pull the head right now or assume the key works. It looks intact. It looks in the correct location but who knows, but I'm thinking of moving on to spark fuel carburetor arena. Jim

Mark, I hear you. It wouldn't surprise me if I destroyed the keyway again because the symptoms are exactly the same as the last time I destroyed the keyway. Jim

Davis I hear what you're saying. The way I'm thinking about the problem is if there's something internal to the short block that absolutely is the problem then move on to another engine but I don't know that right now for sure. If the problem is one of the components you slap onto the short...
