I have a 1942 TD6. My grandfather bought it in 42. Still runs great. I have several videos on my channel and recently posted a new one with my crawler. You can see them on pleasant valley outdoors. Fun machines to run.
To start, you’ll need to turn on your gasoline and diesel at their respective tanks. Then from the operator seat, move the throttle lever all the way back into the gas position and pull the lever to the left throttle all the way back to open the valves on the cylinder head to allow it to run on gas. Press the starter button and adjust the choke as needed. There is no throttle control when running on gas. Once the engine is warmed up, at the same time push the throttle and compression levers forward and it will switch to diesel.
