770 oliver help needed

[hoddykubody]

Fellas I could use your help . I've aquired my FIL Oliver 770 gas tractor and I can't for the life of me keep it going. I believe he had same trouble with it when he put it away 2 years ago. I've cleaned the gas tank out but crap and dirt keep plugging up the small holes in the sediment bowl. Also if I clean the bowl and run it for a few minutes the bottom of the carb starts frosting up. I thought the venturi was backwards but it doen't seem so. Can't figure this out . Hoddykubody
