Hello,<br /><br />I measured with professional equipment for:<br /><br />cylinder 1: 120 psi<br />cylinder 2: 126 psi<br /><br />Conditions:<br />Engine warm, full throttle, handstarting <br /><br />Is it o.k. ?<br /><br />With electric starter I suppose the values would be some higher.<br /><br />What are typical values for this engine under the mentioned conditions ?<br /><br />Regards Nordy

I have seen no spec's, but that is good to go. Should run with 80 psi or better.
