Ok, I hand to put a new starter on my SL780 since it was locked up from the guy a bought it from. So I did a compressiong check I have 150PSI on the PTO and CTR and have 130PSI on the MAG. Since I have most of it a part should I just hone the jug and put an new set of rings to help get the compress closer to each other? The engine has 131 hours on it which is not that much or should I just put is back together and run it?
