Shop around on the net: found the grose jet float valve $$$ (Renners) doesn't seal well; viton tip valve set fits from Steiners or other midwest tractor suppliers as stated; bowl and other small gaskets from Mike's Affordable; there are 2 idle mixture screws lengths also with different threads for varying Allstate or Marvel (same carb.) File or true up the carb mating surfaces as best you can , then set float height.
