I can't resist asking even though I have a strong feeling what the answer is. My Polaris ATV was running fine when I plowed off the last snow last month. I went out and fired it up and it won't idle. Classic fuel contamination symptoms (gum and varnish).

I can take the carb off and clean it out or I can try something like Seafoam that is advertised to dissolve icky stuff that clogs pilot jets. Has anyone here successfuly used this product when they had clogged carb jets?
