340 fuel/ignition issue?
I know the float levels are good, and they are new nitrophyl floats. I'll pull it apart again, check the needle seats are tight in the cover, do a pressure test, double check the fuel wells, make sure the o-rings are in their proper place, check the air bleeds are clear, and lower the fuel pressure a bit.
This will be the second time apart after it started running so rich. I don't know what else there could be though. The weird thing is it seemed to have happened all of a sudden.
