Hey.

After rebuilding my Injection pump my car doesnt rev as it used to do. it idles fine. It pulls happily to about 60 km/h and then the power stops suddenly, just like someting is cutting the fuel... .I did unhook the wastegate from the turbo and it acted the same.I turned the max fuel screw in and the result was just more smoke in all revs. also tried to turn the idle screw and max throttle screw. The only thing i havent turned yet is the governor screw. So the question in here is: what does that screw regulate and where to turn it to get my revs back. Also,what else could be cutting fuel?


Ingmar

 

It sounds to me like aux fuel adjustment is blocked or has no connection the boost pipe from the turbo. So no boost - no aux fuel. Disassemble and check the IP.
- Is the membrane fitted in the right way?
- Does everything move freely?

Before you try to adjust any screws let us know which engine model you have: SB, RA, 1V and so on.
All models have slightly different pumps, so which one is yours?

Unhooking the waste gate with no differences should tell you that without fuel you can't get power...
