    It's all possible. What is that question? The carbs might be a little fat. Give us a shout once you get into it.

    Edit: it might be a lot faster and easier to fix the one cylinder

    I agree, 1 cyl would be easier than swapping motors, rejetting carbs, and messing with the wiring. It could be done quite easily if you still want to go that route.

    Just use the 750 carbs. No jetting required then. Sounds like your gonna swap them, go for it then. Any more Q's post therm up and we'll help best as we can.

    Use the ocean pro air cleaners and the carbs should be close enough that you can tune it to work. The 750 air box is more restrictive and has smaller main jets. Electrics should work. Just keep checking your spark plugs and make sure you dial it in.

    750 and 780 carbs are the same, 38 mm Super BN. Unless the 750's are in bad shape, just use them. Otherwise rejetting is in order. You should be fine with the 780 CDI, it may wake the 750 up a bit.

    bolted on the 780 carbs they have the ocean pro air filters... just realized ill have to swap the Oil Pumps and Motor Mount Plate.. (the 780 carbs have the choke and throttle near the PTO the 750 has them near the MAG ) also i was gonna ask do i need to set 1 of the pistons to TDC before i try and fire it up? i dont know about that part...

    also on the Fuel Spitting problem i pulled my reeds and the one in the PTO were it was spitting was missing a chunk
