Low comperession yet it runs too good ?

samedi 15 novembre 2014

Hello

Please share your thoughts . Yes I am a newbi ! I bought a 84 RX8 a week ago .

I am very good with my hands and enjoy working on stuff ! I have extensive tools !I am 64 retired ...

My question I used a compression tester yesterday to do a compression test on my 8 and I took the shrader valve out . I only got about 10 lbs PSI steady over all three lobes of the rotor .Both rotors test the same I removed all 4 plugs to do the test . I would think it would not run at alll with compression that low ??? But it runs damn good . Compression guage has been in tool chest for about 15 years ,

Can you read the plugs how they look like a convential engine ? One trailing plug looked oil fouled ?

She was hard to start ...but I think part of that was me not knowing starting and shut down preceedures .

I think she needs a complete tune up !!
