John,
Thank you very much for the reply.  It was very helpfull.  I losened the spark plugs about two tuns during the comprssion checks.  Is that the right thing to do ?  I did not take them all the way out because I didn&#039;t want anything to drop in the cylinder.  The engine rpm seemed qute consistant.  However; I did not measure it.  I have a device to do that with.  Would that information be helpfull ?  I have changed the oil filter and the oil already.  I was afraid some of the fluids I used to break the engine free were in the crank case.  That was my main reason for changing it.  Do you have any idea what the compression was when the machine was young ?   If not is there somebody I could contract for this information ?  Once again thank you very much for the heip.  By the way, I really feel fortunate to get the engine free.  It must have set a real long time.  There was about a 8 inch tree growing up through the machine and it was dead !  Thanks Again
