Petcock

My 69 is having fuel issues, with the Petcock open is fuel suppose to come out of both lines ? Because the main is working great lots of fuel pouring out but the other line is maybe a drip. I took the Petcock apart and blew things out as best that I could but still getting same results.

Any ideas ?

They will do that. If you plug the line that fuel is coming out of, it will start coming out the other line. Nothing wrong with it.

Re: Petcock

Interesting, I have a major bog and no power. Any ideas. It idles pretty good but as soon as I throttle up it bogs out and sometiMes dies after it idles back down. It's very sluggish when trying to drive can bearly keep the rpm's up. Can't drive it because of this.
Thanks

Ideas that come to mind are, vacuum leak, dirty carbs, and bad points/ignition problem.

Re: Petcock

I'll double check everything, I checked the timing and it seemed fine, the carbs are clean. I'll check for a vacuum leak.
Thanks for the help.

Vacuum leaks are common around the manifolds between the carbs and engine. The manifolds get hard and crack when old. The clamps for them also stretch out, preventing sealing. Spray carb cleaner in short bursts around the both ends of the manifolds. wd-40 can work but makes a mess. Don't use startng fluid. That shit is bad news. If you notice changes in rpm, you have a leak.
