Viper won't idle

[GibViper]

Parked sled after last season (ran fine), now sled will not idle. Pulled carbs, look very clean, although they have not been totally taken apart and cleaned since I have owned it (two seasons).

Does this sound like a dirty carb issue or could it be something more?

Clean carbs thoroughly every fall before trying to run a sled...

Definitely the sound of dirty carbs. Take the bottoms off and clean out the mains, pilots, and fuel screws.

your pilots are plugged and the pilot circuit passages. take out the fuel screws and pilots and pay special attention to the metal washer, o-ring, and spring under the fuel screw. blow out the pilot jets and pilot circuits on the carb w/carb cleaner and compressed air. also, not a bad idea to blow out those main jets either. i highly doubt that one of them is plugged up tho. once carbs are clean, return the fuel screws to 1-7/8 or 2 turns out from lightly seated.

Sounds like that should do the trick...I'll give it a try. Thanks!
