I recentely bought a 35 chevy with early T.P.I. I drove the car from Missouri to Oregon with no problems. While fixing raddles inside the firewall. I moved the six postion switch which regulates the F.I. lean-rich. Its a hit and miss whether it will start let alone run when you give it gas. Has anyone had such a switch on their T.P.I. unit? If so what starting procedures do you use and where do you run yours at. Thanks Ron
