Thanks Curtis and everyone else, you were right it turnsd out being the regulater, I put a new one on and it works perfect now. I set it at 8 and it stays at 8 I know for 5000 rpms for sure now, but man what is it with the 280 leaking. I bought a rebuilt one through Jegs and it leaks about 1/2 teaspoon overnight the 280 thats been on there for 3 years never leaked a drop. I think I'm gonna have BG rebuild the old one and sell it and buy me a Magnafuel 300 and try them. this first BG has been a good one though I just wanted to rebuild it for a spare.
Thanks Guys Andy
