    slight loss in acceleration

    i lost some acceleration on my 800 it still gets up to speed it just takes a lot longer to get there. the ski doesn't seem to be caviating i think it was the plugs fouled out becuase it got hard to start but they only had 10 hrs on them.

    i cant mess with it for few days but is there any thing else i should check out

    Sluggish?

    10 hours on a set of plugs is not right. I have gotten as many as 200 plus hours on plugs in the Yammy. Check your fuel, might have gotten some High$ cheap stuff. Does sounds like plugs. Do you have a primer on the 800?

    no but when the plugs are new the engine started with ease when it was hot. now i got to hit the choke a little. also the carbs were rebuilt last year. i ran 3 tanks of gas through it 2 from the same station and one we drove to by the lake. im gona go pull the plugs and take a look at them.

    oh and its on the oil pump not premix
