Last year when i had that leaking issue the FIFTEE3 mentioned i called tom and he told me to take apart my carb and clean it myself, so i did. It solved the leaking issue. It was debris from the two holes he punches in the tops to allow for equalization of the bowl. The carb that is currently running the truck has only been taken apart once for me to check for debris after cleaning out the other one last year.
So far i have dismantled the questionable semi working carb fully and checked all jets and gaskets and other items. All ports seem to be free of contamination. It is possible the carb is just garbage to begin with.
I am thinking about just buying 2 more from tom but this time around asking him to not punch the holes in the tops. I want to properly use one of the plugged holes and vent it to a charcoal canister so i can knock down that after running fuel smell a bit.
FIFTEE3 have you changed the getting at all? You running a stock cam?
