Advice desperately needed. My 65hp Perkins
4203 starts fine, runs for about five minutes but then slows down and quits, it does this repeatedly and is driving me crazy. I have eliminated any and all fuel
supply problems that I can think of. There is plenty of fuel
getting to the injection pump inlet but the engine
refuses to keep running, I have even removed and cleaned the spill return line and checked for looseness in the manual stop control. Any suggestions please.
