gaining compression out of a .21 nitro engine??
does nayone know of any little tricks that would gain compression i heard that if you take out a shim or two from the head it can gain some but any other ways other than pinching the piston or is pinching the piston the only way??

you can pinch the sleeve by using a pipe clamp. or get it done professionally in the states from OS rocket.
what engine you got?

my experience..i have pinching about 3 -4 sleeve. yes the piston will get very tight on the sleeve but the compression is not. when pinching the sleeve is not 100% perfect circle anymore. when piston compress, some of the consumption gas can flow between the piston/sleeve..
the best other trick is, try to use other/different used piston or sleeve. for example my STS piston have wore out. so i use Hyper 8 port piston on my STS sleeve and now it is very tight like new one. i have to break in once more. and the performance is not bad..
