Jgoodsell 19 #1 Posted June 5, 2017 I have an Onan engine that seems to like to governor hunt. If I feed it a little choke it smooths out, but it smokes a little when I do that. I have already cleaned a carb thoroughly, replaced the carb with a know good one, took apart and resealed the intake, replaced all gas line, took apart and cleaned the fuel pump, replaced the vacuum hose for the fuel pump, replaced the bung on the gas tank, replaced the fuel filter, and I'm sure there is something more have done. She has 783 give or take a few hours. Valve adjustment was done by a buddy. Can anyone suggest something I might have missed? I did not replace the fuel pump as it looked good inside.
