Thread: Need help on understanding gas milage

Tweet

so about 200 miles and 20 gallons??????


Its hard to get ackward figures on a single segment/fillup unless the tank is full when started and then filled to same point when checking----------on trips I fill up before start, log milage and gallons at every fuel stop--figure by both segment and total miles/gallons at each and every stop-this way as distance and miles increase the total running numbers become more exact plus I can see what each segment does(mountains, curves, 2 lane , express/interstate)


But knowing the carb works pretty good around 68 jets primary, timing set to max without spark knock high vacume setting, no windows open, moderate acceleration and longer coasting to stops-----------

I can change out the carburator or change the jetting to a 68 primary and 70 secondary. As far as the RPMS goes all I can do is install a 700 r4 transmission. The rear end is a 2.73 now and I can not go any higher.
