Is my 340 Overcarbed? Avg 5-6 MPG

Really great to see you solved your problem...all with the help of the FABO Brothers! So, I am assuming it was the fuel pickup height. ---- Recommendation: DO NOT BUY your fuel pickup off Ebay, use Year One or a reputable dealer. I purchased a 3/8 pickup that would not reach the bottom of my tank and had to repurchase one from Year One. ---- Frustrating problem, GLAD U FIXED IT. :cheers:
