I just purchased a Case 930 with Propane as the fuel source. The tractor has been sitting for two years without running, but it ran fine prior to storage. When the tractor was started, the engine would not go above 650 RPM without choking out. I tried again the following weekend and the engine ran fine the first try. I shut the engine off after running ~1 hr. I tried running the engine again 4-5 hours later and it began choking out at 650 RPM again. Does anyone know what the problem is?
