Thank you guys, great info . I'll take the carb off after work and see what's going on in there. When I bought the tractor it had been sitting for about a year and a half with a tank full of gas. The carb was incredibly dirty on the inside , all sorts of slime and it had all this crystal like sediment at the bottom that had nearly eaten a hole through the bowl. I wonder if the old gas caused damage to anything else, like the fuel pump or the needle valve seat, although if I remember correctly the seat is brass. Either way, I will report back this evening. Just in case, what model carburetor is on these? It looks almost identical to the #30 that's on the K321 but it doesn't have the #30 stamped on the inside.
