Don't know if you're still having problems, but I had an issue with my Major Diesel where the fuel cut off mechanism was sticking inside the pump. You just take off the side of the pump and free it up, and be sure to get everything right in there. I had a screw riding inside there loose that bad backed out. Once I got it free, then put the rack all back in line, it runs like a top again.
If I could get the PDF files, I would appreciate it too. email@example.com
