I guess "little things mean a lot" really applies here.

I guess... Really surprised that this little slop was causing all my issues. I would assume that if a nut was used to hold the flywheel on then this might not be an issue. With only the pull rope starter this most likely has allowed the key way to become worn enough to not allow a standard key to keep it in time.

Glad you found it, an thanks for the lead.
I have a push mower that may be suffering from the same issues.

Back to the drawing board! I made sure the starter was tight against the flywheel. I swear this thing is possessed! Replaced the flywheel key with a larger one, and had very little "slop" but wasn't as tight as I would have liked it. While testing I took videos every 10-15 seconds, First minuet or so it ran perfectly smooth with no missing, next minuet or so it started to pop once or twice every 10 seconds or so, then this is after about at the three minuet mark, really starting to degrade and miss badly then then the starter started screaming like a banshee!

I wonder if they still have starter assemblies for this? I hate to give up with about $40.00 invested.

I know you have cleaned the tank and carb but being that it runs well could it kicks up dirt or scum and clogs up the pick up screen? Sounds like a fuel hiccup.

Just a thought.

Small Briggs....been awhile but What kind of recoil does it have? The one that bolts to the fly wheel and has a square peg on it? Or the cup and dogs?

That's the recoil clutch, it will rip the rope off and damage the recoil., pull the cover, spin off the recoil clutch, sand down the crank with sand paper and emery cloth, put a small drop or two of oil on it then reassemble.

 

I do it all the time on thoses little engines.

I plan on doing the sanding and oil again, but doesn't explain the running good then degrading to missing and backfiring. I'm not done with this yet.

Fuel seems fine, after a fit of missing and backfiring I reset the key and it purrs like a kitten, then acts up again. Every time I pull the flywheel (four times now) it runs fine for several minuets then... well you saw it. 

It has the one that bolts on the flywheel with the square peg.

The push pin for the points? Is it possible it or a valve is sticking when it gets warm? I have a Briggs I quit using because of the valve sticking. Someday, I want to take it all apart and run a drill bit in that guide.

Still researching this. First, I did not know that there are two different type keys, one for electronic ignition, and a different size for points. I assume the new points kit I bought should have the correct key, but that key became deformed earlier on, and I used a key from my parts bin. Also I looked up the correct parts for this, and a tool that should allow me to tighten the starter correctly.

This is what I found at the Briggs site;
61760 Key for Points "Call Us" I have to order the points to get this.
399671 Clutch, Starter Used after code 6405220 $23.50
294628 Points kit (includes key 61760) $13.11
19069 Flywheel Puller $12.98 (Is this what I need)?

So basically another $60.00 or so. hmmm Now I am wondering if it is worth it. I checked Home Depot and these are running around $250.00 or so.

I'll probably go ahead and order these parts, Thanks for the help.

Before ordering parts I gave it one more try. I cleaned the starter, found a tool that let me tighten it good. Took it outside and started it up. Running good, so I let it run while checking on it about every 10 minuets. After 45 minuets this is what I found. Cleaned it up to see where it is leaking. Update, I have it back in the shop. Added oil, no leaks while NOT running. Hmmmm.

looks like the seal if only when running, could be the flywheel bearing plate seal or plate to block gasket.

I wonder if tapping in a flattened key may have messed the seal up? I am getting good at taking this thing apart..... (said with a sarcastic tone).

Naw, when the keyway meets the seal part of the crank it slopes up.

Have you looked at just replacing the motor with one of the clone engines? They have a 3 hp for 99 bucks.
