Do you know the figure for the right compression ratio for this pixy after getting about .018 to .021 clearance?
I may have someone here that have the compression gauge that i can measure it and compare with your figure.

I've sanded about 0.007 off the top liner, and putting the 0.004 shim in there. From your calculation, i believe i should have about 0.021 clearance now. I'm going to try and run it with McCoy MC-8 and 30% Rocket Science Fuels this weekend and see how it goes.

all you need to get your head clearence is a piece of solder, like dean's or something about that thin, and a set of calipers. just bend the solder over and put it through the glowplug hole and turn the engine over by hand. the solder is soft so it won't mar the aluminum at all. then take the solder out and measure it where it was pinched with your calipers. .030 is pretty high. that doesn't sound right. even .21's are more like around .020-.025

Woow, that's relatively cheap Which shop in HK is that? A friend of mine just came back from HK and bought the engine from Harmony for USD 320 (close to HKD 2500)!!!... RC Model Online had theirs on their site for USD 457.14 !!!
