[Richard Fink Sr]

Hi all i have in last few days tried starting a tractor that sit for over a year. Problem good spark so went to gas nothing at carb. cleaned sediment bowl, no gas removed sediment bowl from tank. screen and passage way plugged solid wit what papers whit stuff. what is this, from moon shine in gas. Have it running some what now but may need to remove carb and clean it. Anything i can run through it that will dissolve this stuff. just put on new sediment bowl unit.
