Looking at your tank placement the fuel supply comes out of the top of the tank which means the pump has to pull the fuel all the way from the bottom....and it appears to be a significant distance. Two solutions....new vacuum pulse fuel pump and see if that helps or a 12v solid state fuel pump...

AI confirmation To install the governor shaft seal (OEM part 692407) on a Briggs & Stratton 195707 Spec 0468-E1 (or similar horizontal-shaft single-cylinder models), the seal goes in from the outside into a recessed area behind the governor arm/lever. Some of these engines left the factory...

I asked because I knew, not because I didn't.

The old "ethanol" trope.

Parts cannon.

Any good belt supplier/stockist has a belt measuring "stick". Ask them if they have one before you go. Take off the old belt and they can supply a suitable replacement.

A "single lock washer".......the Belleville or are you talking about a split lock washer?

That and the fact that without the adapter the bolt was probably bottomed in the crank hole and the clutch wasn't contacting the shaft face. Any torque applied to the bolt only torqued the bolt...and I'd be suspicious of the bolt from here on out.

Kinda don't think you need 120psi since the gauges only go to 100 psi. 50 psi will do as you are measuring the relative sealing ability of valves and rings......

Yeah....I had a KTM 250 XCW that went to 220 but the head was shaved 40 thousandths and the cylinder trued 5 thousandths and that necessitated using premium to keep from detonating.

Effective compression ratios of piston port two strokes are typically much lower than an equivalent four stroke of the same bore/stroke so there is no apples to apples comparison. Typically two strokes are anywhere from 5:1 to 7.5:1.

Precisely. There is a thing as too much lubrication. Are the balls supposed to skid or roll. I'll take roll every time. Too much creates a hydrodynamic wedge of lubricant just ahead of the ball and with nowhere else to go the lubricant makes the ball, with whatever tolerance is left to the ball...

No. Float No. Float/Needle just regulates flow depending on the fuel pressure. If pressure is too high it overpowers the Float/Needle. 1 psi is enough. Little electronic pumps can run continuously.

Differential tester....

1-877-473-6767, dial #2 to reach NGK support. You send them images of a suspect fake plug and they confirm whether it is or not. Champion may have the same service. Fake Chinee plugs are a real thing.....
