  If your Hatz Diesel Engine doesn't start but the starter is turning, make sure the speed control lever is in the 1/2 start or max. START position and fixed there. Check if you are out of fuel and refuel if necessary. You can also activate the feed pump until you hear fuel flowing back into the tank through the return line. Systematically inspect the entire fuel supply, including the feed line, fuel prefilter, fuel filter, and the function of the feed pump.
