Hatz 1B30 engine over speeding

[FendtLad]

Hi all,
Just wondering if anyone here is familiar with the Hatz 1B30 engines. We have one on a weber plate compactor. Engine has about 330hrs on the clock. Engine starts fine but goes straight to full throttle. So far we have removed the side cover to check for anything broken (linkages/springs) everything inside looks perfect. The governor arm rotates the bottom of the pump so nothing looks out of place. We thought maybe the operator has filled with petrol instead of diesel so we drained tank and filled with fresh diesel. Any help would be appreciated.

Has anyone been into this engine since the fault occurred? I've had one with the govenor mechanism was installed the wrong side of control lever on the pump so the pump could rev out uncontrollably till fuel was cut off. The pumps are really expensive for what they are and dead simple to control, just a lever on the pump body (all internal I'm afraid), that adjusts the fuel rate. Can't see how the govenor mechanism would fall apart but maybe that is somehow damaged internally? Without taking it in bits, I don't think there is much we can help with as there is next to nowt of the fuel system on the exterior of the engine.
