Briggs 19.5hp won’t turn over on compression stroke
I have b&s model 31p677-0912-g5
It drags on compression stroke, I’ve changes starter, solenoid, battery. Still does it.
I put my hand over carb intake and it will start when I do that. It still drags a lot but will end up firing over.
Take spark plug out and it turns over fast.
I’ve read about compression springs inside of some higher hp motors. Does my motor have one and do you think it’s the compression spring? Is it part of the camshaft gear?
