Default Re: Compression question

Is it brand new? They require at least three or four tanks of fuel run through before they are broken-in and at full potential.
(I'm assuming you are asking about a chinadoll in frame motor)
If more is better, then too much is just enough.
If you can't afford it, build it yourself.

120 to 165 will usually run well - higher numbers usually mean faster speed available

had one 2 weeks ago at 175 & immediately guessed (correctly) that he had gotten straight oil into the motor
Sometimes I sets and thinks, sometimes I jes sets.
