RE: IS ASP 52A 2 STROKE GOOD?
I own several Magnum and ASP engines.
All are reliable, but people used to tuning other engines may find the ASP/Magnum's more difficult because the needles are far more sensitive.
I find that 1/4 to 1/2 of a turn is the difference between an engine that will not start to one that runs perfectly... where as with other engines it takes more to achieve the same. Once you get used to this and find that 1/4 tuning window, the engines do well.
They run just fine inverted too.. no difference in rpm's and performance what-so-ever!
Re: Dale's problem...
The "the carb is much lower than the standard upright mount. This can result in the fuel tank being mounted too high for an inverted engine." only affects fuel SIPHONING when the engine is sitting on the ground and/or you are about to start it. That DOES account for Dales problem of fuel being siphoned out SLOWLY though.
Once started the engine behaves the same upright or inverted. It makes no difference to the engine.
The carb height difference ( which is miniscule btw ) produces an immeasurable pressure difference, the same as putting something .5" higher in our atmosphere.
If your engine is behaving differently when inverted than upright, the problem lies elsewhere... e.g. tuning is permitting the glow plug to see too much fuel, etc.
