The sled sat for three years, put all new gas in with seafoam. Problem, cleaned out carbs but still getting little rubbery balls in the carbs after running it for a while. The sled then wants to bog down. Clean carbs out again and the little balls are back. Solution?

Sounds like the tank is full of stuff or the fuel line/pump. Clean out everything - taank pump and lines.

Will do, thanks,

I had an outboard motor that had the exact same problem. You have a black rubber part breaking down somewhere in the fuel delivery system. If you dont replace that part you will possibly melt down on a wot pull if the carbs get that stuff in them again. Check all componants as stated above and replace anything suspect as well as the fuel filter
