Yea in your carb......that film is all thru the combustion chamber. If the exhaust can't get out at high RPM same problem. But it's your mower and your ever growing grass.a reply to: Bluntone22

You could also have a stuck float or a small hole in your float.

Exactly, good point. I didn't ask hrs on unit.
I'd do a "finger" compression test before buying a gauge, it will show failure w/o it., but drop a teaspoon of oil in cylinder, or fog before tests, crank a couple times to lube walls and rings for accurate reading-pressure bleeds past easily when rings are not oiled well.

Excess carbon makes big issues as well on high hr units. In some cases you will decrease the cc of volume in the combustion chamber and over compress it, or make your mixture rich running same fuel into smaller area.
Increasing carbon and wear on rings and valves

You can burn minor carbon buildup off the inside of an engine with a setup like an IV drip. The target is a 50:50
Ratio of water and transmission fluid.12oz each.
1 drip per second-ish directly into the intake when the engine is hot.
It will smoke like mad out the exhaust, keep enough throttle on it to stay running, till it's empty. The water creates a wicked steam, loosening the carbon deposits up and the t fluid washes it off like magic.

Also I would run a 110 race gas mixed with 96 pump 50/50 for a tank. It's like engine renewal-on Stock jetting.
