John has done a masterful job installing the rebuilt generator, carburetor, and fuel filter.
The generator performs well and looks great.
The Stromberg carburetor may be fine, but my test run didn't go so well. The engine started easily, but really raced, so I adjusted the fast idle screw to 1000 RPM. The engine runs at idle at 375 RPM when warm.
On the test spin, it died at the bottom of the hill when I stopped. The car has much more power. The acceleration is amazing. It reminds me when the car was stripped of hood and trunk, fenders and doors and top. It just flew. That's how it is now. I think there were major problems with the Carter carb.
But now, when I start up the hill it quits.
It could be starved for fuel, so John will rebuild the spare fuel pump so we can switch if need be. I have an electric fuel pump that puts out 10 lbs pressure, but I only use it to break vapor lock or if the car has been sitting a few days. I give it a few pumps, shut it off, and start the car. I was only able to restart it by turning on the electric fuel pump and keeping the pedal to the floor (the car was fully warmed). I made it home, but I went gingerly, not giving it too much pedal.
Daytona Parts sent the carb back without the fast idle spring. I called, but they said emphatically, with 30 years experience, it is absolutely Unnecessary. Backstory: Six years ago I called them to see if that spring came in their AAV-26 kit. They said No. The spring has to be taken off another AAV-26 so we only do that if you have us rebuild the carb, a $300 job. So I sent the carb in with a note making certain they would replace my bent up spring. In the past, Without that spring, the choke plate could flip flop, open and close, and the car would buck. They said they guaranteed to would not do that with the spring off the carb. The huge amount of air being sucked by the carb would keep it open. Once we resolve the fuel supply issues and adjust the carb, I'll take it for another test run and see what happens. Can you tell I'm skeptical?
