Bill!
After your answer about my pump problem I have followed your advise and run my engine with several tanks of fuel, but it seems my pump is gone. The engine doesn´t work reliably and I don´t want the risk of having an "out-landing" with my scale CUB. At the moment I can't get hold of a Mk II pump and carb from the Swedish dealer. The question is weather I can fit a Mk III pump and carb to my old motor. The motor has not had so many hours of running altogether and it would be such a shame not being able to use it at all.
Regards
Peter
