im having problems with my motor burning some magor fuel. We did the cam break in tonight and the thing burned up 10 gallons of e85 in 30 min . Im running a mallory comp 140 pump with a "deadhead" regulator, no return line. Carb is a 750 holley hp alcohol with quickfuel e85 metering blocks. Im running 90/96 jets. right now the idle mixture screws are backed out 1.5 turns for a starting point because I havnt had a chance to adjust it yet. What would be causing it to burn this much fuel? would running no return line have anything to do with it? would jetting it down to say 85 in the primarys help?
