I don't have any problem with the four strokes. As soon as they make one
that doesn't cost 2-3 times as much as a two stroke, runs when you want it to
without working on it every day and one that won't shake my airplane and radio
to pieces I'll be happy.

They have answered all but the cost factor... I haven't had to touch the needle valve on my O.S. .91 FS in over 18 months (puttng several gallons through the engine.) The vibration was no problem at all... not any worse than a typical 2-stroke. the cost... well it was $250 for the engine... which is right at 3 times the cost of an equal power 2-stroke. But it burns enough less fuel... and is so much more reliable I think that made up for the cost difference.
Only problem I ever ran into with it was: I improperly tightened the muffler... and ended up stripping out the threads. ($25 for a muffler... [
]) My fault... not the engine's...[&:]
How many 2-strokes can you take out in any weather from 32 F to 120 F not care about the humidity... and not have to change the needle one click?
