Guess the time is here to do something with my ole 1855. The motor smokes pretty bad when I first start it up, still runs good and fires right up but she's down on power. I'm thinking about a 23hp Vanguard conversion, Jim's tractors has a complete kit w/motor. Has anyone used the Vanguard in their tractor and if so how do you like it? I'll keep the Onan and rebuild it but the main reason I'm considering the Vanguard is that I have to take the FEL brace loose at the frt to get the oil filter off of the Onan and I wouldn't have to do that on the Vanguard.
