I just got it here and am doing a once over before the purchase i have till the weekend. So i ran the comp #s and they are 75 accross the board give or take a few psi and they all were checked dry and cold the motor hasnt run in a year probably and i pulled up the idle lever and tested one and it made no difference. I tested with the other plugs in and out both no change. What is a good comp # for this motor and with it sitting and dry were these bad readings? I am gonna try a decarb in the next day or two before i condemn it but need a little advice from someone who knows these motors. I also would like to here about the oiling system for this motor was it reliable or is it maybe to blame for the low #s Thanks
