Turns out they're not supposed to fire when in N

Started it and tested spark in gear both 1 and 5 have spark.
This has been quite a learning experience.

NOW!!when put in gear low speed still rough then as the rpms pick up it accelerates up and down by its self.
No water in the fuel.

Get it figgered out ???

1 and 5 don't fire while in N..
Talked to the owner and he said they ran a bunch of contaminated fuel and it started running bad.'
Next step is to check the filter in the Vapor Seperator

You said there was no fire on one and five but then you said they ran contaminated gas through the carburetors, did you test for spark and if you're getting spark then it's probably a fuel issue in that case started the fuel filter and then take the carbs off and do a flip over cleaning

Could those 2 plugs be contaminated ? Fouled ?

Read #2 #3 and #6.
Its designed to not fire on 1/5 when in N
No carbs DFI
The vap/sep filter or the injectors might be clogged.
Will dig into that when it gets warmer. My fingers don't work well when cold.
THANKS!!
