    Default 96 XP800 high speed adjustment clarification

    A little history of the problem:

    I purchased this ski about 3 weeks ago after if had been sitting for a bout a year. It needed a starter so I installed a new one and fired it up. Seemed to run great at first. Idled a little rough and would die if not given a slight amount of gas but overall it ran pretty strong. Lately after riding at 1/2 throttle and up and then shut off quickly it would have a hard time restarting. I would need to hold the throttle wide open as if it flooded itself. So I pulled the carbs off last night, found the internal filters were pretty badly clogged and proceeded to take the carbs completely apart for further cleaning. the carbs are misisng the plastic caps that people refer to that stop from making big adjustment changes on the HSA. I'm also changing the gray fuel lines before taking it out again so it doesnt happen again.

    Fast forward to the question.

    I've searched and searched and found that everyone mentions high speed adjustment screw should be set to "0". In the past I've always done the adjustments by taking the needle all the way in and then backing out the needle the recommended amount of turns. Does this mean that I should screw the HSA all the way in and leave it? This doesnt make sense to me and seems that fuel would not be allowed through the jet or it would run extremely lean. Can someone please clarify this for me! Sorry if this is a repeat question but I wasn't able to find out any other info doing the searches!

    Thanks in advanced!!

    The "0" setting means screwed in clockwise until the screw stops turning - and don't crank hard on it.

    Any turn specification (1.5 etc.) means close clockwise and then loosen/open counterclockwise.

    HSA at 0 is not necessarily a true closed. There is some fuel getting through in a very small amount because of the way it bottoms out at the threads (not the pointed tip).

    That said, the HSA becomes a more important factor with aftermarket flame arrestors or aggressive jetting. The LSA has the largest effect for a stock induction setup.

    Thank you for the clairification. Unfortunately I am not 100% sure one what all has been done to my ski as far as jetting. I do know that it has a West Coast flame arrestor, Rossi pipe and has been rebuilt once, maybe twice. Also has repitched impeller and a west coast nozzle with the VTS system removed with a 4" extension from the 95 XP model.

    Any recommending intial setting? It was about 1 turn out when I took the carb apart to start cleaning it but the plugs have always looked pretty dark as if it was running a little rich.

    thanks again for all of the help!
