Need help with edelbrock 1406 carb

Good info, but I think the issue is/was his fuel pump mounting bolt hole.
The OP started a thread on that.
Just to get back to the original problem - if you have a good in line fuel filter, how did the crap get into the carb and hold the needle up to flood the carb? Not once, but then after you cleared it using the TrailBeast method, to have it happen again? Maybe the crap is being manufactured in the carb... you are using fuel with ethanol in it aren't you?
