heres the scoop. I took out my spark plug and did a compression test. Both front and rear tested 90 lb/in^2. I think this is low compression. Im right arent i? whats a new motor run??

thats a little on the low side, but the engine should still run. the fsm says 85 is minumum
a rebuild starts at about $1700

so it was 3 even bumps at ~90 each on each rotor?

well it was kinda wierd. no matter what. The first pump on the first rotor was 60 then the next went to 90. It stayed at a constant 90. The rear went to 60-90 and the bounced around like 92-67-90. You think if my 6th ports are wired open that would hurt my compression?

joep

and to put it in perspective?? whats a rebuild start out at?? how long does it take normally to go from 90-85. Worth doing a rebuild right now??

you really need to find out what each rotor faces comp. is.

mine has 75psi on each rotor face and on each rotor. and mine still runs pretty well. battling a fuel issue right now but when fuel is ok it still runs good.
