Hello everyone. I have had this 642b for 2 years. Everything worked fine except for a blown fuse if I turn it over too much. But usually it starts right up. Anyway my problem is, it hasn't been started since April. I just tried and it turns over but it doesn't seem to be getting gas. I pulled the gas line off but the unit (sorry not sure of name). By the distributor and there is gas to that point. I shoot some starter fluid in the carb but it won't start. Any ideas? I'm a rookie mechanic. Thanks
