    1996 polaris slt 780 carb sync

    So the jet ski runs now (!!) Im pretty stoked about that, but I noticed that the butterfly valves for the choke seem to be slightly off. When I apply full choke 2 seem to be at the same position but one seems to be barely more open. Is there a process that I should follow to correct this? Thanks, Joe

    Ok I got them nearly perfect to the point where I cant adjust them any better. Looking at them when the choke is not applied they look to be completely vertical, but ill attach pictures so

    Looks good! It really is trial and error. Adjust one, go adjust the other. Then readjust... As I am sure you found out...

    Open everything a bit more 1/8 than stock. I usually do plug chops to first check the burn condition. Kill the engine while holding the throttle wide open on the water. Pull the plugs, and look at them. Chocolate brown is good. White/light gray is lean. Dark brown/black is Rich.
