I have a 1955 300 IH Utility That will start and idle fine, but when I start to rev up the RPMs (give it gas, or pour the fire to it)it sputters and shuts off. The tractor was converted from 6v to 12v ignition many years ago and had ran fine for a long time, then started to have trouble with throttling up the rpms. I have replaced the distributor with an electronic ignition set, and checked the amperes across the unit with a volt meter and some math. Everything seems to be within amper specs of what is recommended for a 6v to 12v conversion(i.e.I tested the voltage through the coil and distributor and coil and got 11.95 volts then found the ohms across the coil. + to - side was 3.97 ohms and then divided the volts by the ohms to get around 4 amps. Which is what was recommended for a 4 cylinder tractor. Then replaced sediment bowl and strainer, checked and cleaned fuel tank, fuel line and filter, and cleaned carburetor(but not sure if carburetor needs rebuilt or not). Fuel was flowing to and through carburetor.I set all adjustments to specs, but tractor still wants to shut off when throttled up. Any Ideas please?
