Is my 340 Overcarbed? Avg 5-6 MPG

If you got it driving decent, you're still going to have to open up pvcr in primary metering block
to get wot afr in the ballpark. Add 2-3 jet sizes to secondary before doing that. Also, you shouldn't
need that green pump cam (your main complaint in the beginning was poor fuel mileage, right?) To
me, if you need that agressive of a pump shot, your idle feed restrictions need to be opened up
.002" or so. It would be a shame to have such a nice motor, and not tune it to its' potential.
