Hi all. I have an IH 300 Utility (1956) that I have a strange issue with. It has never liked to start in the cold (40 and under). When I go out and try to start it, it will run for just a second and stall out. When I crank a second time, the top half of the carb gets frosty and gas starts dripping out of the bottom of the carb. I figured out this winter that if I run a hot air dryer on the carb for a few minutes, then blow some warm air into the air intake as I"m cranking it, it generally starts right up. Today I did exactly that and headed out to get my truck out of the mud (I"ve had a tough day). The tractor ran fine and normal all the way out to my truck. It was up to operating temperature by the time I got there. I chained it to my truck and started to lift the bucket and it stalled out. Now it won"t start again. I crank it and gas leaks out of the bottom of the carb. Blowing warm air on it does not good now. I checked my plugs and they don"t appear to be getting gas (not wet at all). Any ideas what would be wrong with it? All I can think is to take the carb apart and try to clean it, but I want to be sure I"ve tried all other options before I go down that road. I have a hard time finding parts for this thing and I don"t want to mess up the carb gaskets unless I"m sure it"s necessary. Thanks.
