Thread: 305 Update: new gaskets, Dieseling, misc

Yeah Jerry, but your customers are dealing with engines that are built to the nines, pushing the envelope on compression & timing. This is a basically stock 305 with a mild RV style cam, so the selection of a fuel source is not nearly so critical. Much worse to go to a Shell station that gets ten customers per day than go to QuikTrip where they empty their tanks every three or four days, IMO.

Pretty sure he already addressed the turns out on the idle mixture, several posts back but I could be wrong.

A very good tip on the older GM distributor, and the tendency for the advance mechanism to get sticky and cause the shade tree mechanic to recommend all kinds of "fixes". Maybe a new distributor needs to be on the Christmas list.....

Little Chevy, tell us if you're chasing dieseling or pre-ignition, and while you're in there check the back of your intake really carefully with a mirror and light. That "china wall" gasket across the back of the intake to block is a common source for oil leaking on the SBC.
