Hi everybody, i am new to this site, but wondered if any body can help with my dilema, i have a ossa 250 mar which is running a standard bore, did a compression test this

evening and got a reading of 77psi. Squirted some oil down the bore and then got a reading of 88 psi. Can anybody tell me what psi would indicate a healthy engine.

Thanks HIGGO.
