hey, i just got into this club but yah, i got an 88 fc n/a and the engine isnt too great. So i was doing a compression test and found that the leading rotor had great compression but the trailing had 0...i just wanted to know if its possible to have 0 compression even when the other rotor has about 91psi of comp. Also the thing that happens with the engine is that at idle its kinda shaky and when i accelerate it hardly goes...like i mean HARDLY!...it seems like it has barely any power..but yah i dun wanna make it too long so any help would be appreciated.
