Sascha, on our 77s it shouldn't be as much of a problem as Jeff said because we have a fuel return on our carbs. The PO apparently had an issue because when I bought the rig it had insulated soft lines running to and from the carb. I swapped them out with the factory hard lines, but have never had a problem either before or after. Can't explain why though since I run the same gas as everybody and go to the same altitudes at the same temperatures. Wish I could be more helpful
