Proper gas for 374 engine

Posted by don1260 on 2011/2/21 17:36:02
I have a Caribbean that had to have the engine rebuilt.
When they went to start it after the rebuild...it started squirting gas out of the bowl and the fuel fuel pump wasn't working. My mechanic said the the ethanol in the gas at up the rubber in the fuel pump and bowl. He also said because of the compression ratio I have to run an avgal mixture or I might mess up my pistons. Does anyone have problems with todays gas in their 374's and how do you cope with it? Thanks for any help on this. Don
