RE: Inverted 2-stroke with Perry Pump problems
The REAL problem is the inverted two-stroke engine.
There simply is no way to start these engines without running into problems, especially if you want the engine start as easily as it does when side mounted or upright.
Four-stroke engines have the valves in the head to alleviate the problem of too much fuel in the combustion chamber.
"Just say no" to inverted two-stroke engines and your problems will disappear. No pump or regulator that is made today will prevent fuel from pooling in the head of a two-stroke glow engine. Sorry.
