98 GTX Limited dogging issues

[bkluever@charter.net]

Took my ski out for the first time today, and it fired up nicely. It bogged a bit on the start but then took off. Each time after it was a little slower getting up to speed. After a while, it wouldn't go past 38/39, but the top end has been 55-58 otherwise. Last year I had the carbs cleaned up and one of the hoses for the gas lines replaced. I put new spark plugs in, and premium gas. Is there any easy trouble shooting things to do, or should I take it to the shop? Sea foam?

Whatever you do, do NOT use SeaFoam. It looks like you've been around awhile, but do you still have grey tempo fuel lines?

You replaced one fuel line? Go ahead and replace ALL of them if you have the grey lines. Make sure to clean/replace the fuel selector. And I'm a firm believer of putting a small inline fuel filter just before the carbs. A "fail safe" to make sure NOTHING gets in those fresh rebuilt carbs. By the sounds of it, you will have to take them apart again and clean them.

BTW you weren't overheating where you? What do the new spark plugs look like? Can you post a picture?
