Dieselpumpuk is known for their poor support if you don't treat him like he is a god, much like "uncle Kent" at Mercedes$ource.


Check your chain timing. Verify crank:cam are in phase. Make sure supply and return hoses are connected in the correct order to the tank. Get rid of the stock turbo, its a horribly inefficient piece even for that time period. Check the throttle stop screw adjustment, if its adjusted too far in (more throttle range) it will overpower the ALDA/governor, causing overfueling no matter the governor settings. Make sure the rack limiter is installed, it MUST be installed to prevent over fueling at full throttle, there is no external way to limit fueling like on the M pump with its stop lever "ALDA".
