Hey guys i have a 94 zr580 carbed i just picked up. Motors been gone though all new gaskets, seals, pistons etc. The sled ran great the first time i started it, but now when it does start it will only run on 1 cylinder. I have cleaned bouth carbs out good changed every gas line, have spark on bouth sides and it still only fires on 1 cylinder. Any suggestions???

What kind of spark? Are both nice bright blue? What are your staor ohms?

Ya they bouth have blue spark but it looks a little weak. So i guess next would be to test stator? Do u have any videos on a non efi stator test?? Im really trying to get this figured out because were suppose to have 5 inches of snow by tuesday

have you broken it in yet, tightening the head nuts after each heat cycle?

No it has not been really broken in yet. The frist night i got it started it only ran on 1 cylinder because the floats were stuck in the one carb, after cleaning it out it ran great. I took 3 trips around the yard with it not even 2 10ths of a mile. I shut it off tightend all head bolts and cheaked evenything over. Now when it does start its only running on 1 cylinder. Im thinking maybe the fuel pump???? The sled sat in a barn for about 3 years before i rebuilt it.

New plugs in it?

well i got it figured out that it was a problem with no pickup in the tank, and the slides are a little off. Thank you all for your help
