Have checked firing with tester all plugs firing.when cranked the engine will run for a little while but will pop like a cylinder is not firing.

Rebuilt carbs last summer, Motor ran fine until I started the motor to winterize. The engine flooded and would barely run. when I pump the primer bulb fuel come out the center carb.I removed the carb and checked the float adj. It was ok and there was no trash in fuel.needle and seat look fine...
Don't know if it is flooding or and ignition problem.the primer bulb will not get firm when pumping. At first I thought the left bank was not firing. I switched the power packs which didn't seem to help.It is blowing alot of oil when running. The compression is good on all cylinders. I rebuilt...
