I bought a '75 EB from my dad last year. It sat in his barn for the last 14-15 years. After I got it resurrected (oil change, drained tanks, fresh gas, new accelerator pump, new fuel pump...), it still doesn't run reliably. Sometimes I get 10 minutes from home, sometimes 30 to 40. Then it dies. It seems like it just plain runs out of gas (Yes, there is gas in the tank). When it starts to die, I pump the crap out of it and can limp into a parking lot...usually. I am only running on the aux tank (To eliminate the possibility of a rusted main tank plugging things up), and have already pulled the screen off the pick in the tank and added a filter jsut outside of the tank.

I'm at a loss for where to look next! Anyone have any experience with this?
