I have a carb percolation problem with my M15A. I checked the fuel pressure, it is 4lbs. The float is also set correctly. I don't have a fuel pump shield yet, but I suspect that it may help some but the fuel is boiling out of the carb fuel bowl throw the anti-percolation valve (as it should when the fuel is too hot). It appears to only boil when the engine is at the operating temperature and the truck is shut off. It is less of a problem when the hood is raised after shutting the engine off.
My question is:
What is the best way to raise the boiling point of the fuel?
I don't have access to non-Ethanol fuel. I have heard that adding Diesel to the fuel helps. Also MMO.
Any suggestions?
Thanks.
