vm 26's...

just got my engine back together with a fresh 1075 kit..put my carbs on and it fired up but only the 3 & 4 cylinders..thought probably just clogged...took them off and checked all the jets and passages...all seem to be clear..put back on and fired up again...same deal...sprayed some carb cleaner in offending carbs and they started to fire...now runs on all 4 but ruff..and so you know i have brand new intake boots...getting great spark...any ideas?

Clean your carbs again, that is your problem.

actually..it was a coil wiere grounding on the tank...
