Anyone do lawnmower or small engine repair? Question on no start

Took the carb off and blew everything out again including the banjo bolt. Very clean, no obstructions in it. Replaced the spark plug with a new one and replaced the fuel lines. Fresh gas in it. Compression was 85 psi and leakage was 25% (middle of green). Ran it with the muffler off and still had the misfiring. Getting a decent vibration now through the whole mower, wondering if something internally is broke/breaking.

 

Turns out the upper main bearing is trashed causing the flywheel gap to change and causing the misfire. Not worth fixing

 

That sucks. Well at least you can move on and stop fighting this one.

 

that would do it...
