Reply to "No gas -when starting cold"

It sounds as though you may have two separate problems. Since you have changed the carb. so many times I think it's safe to assume then problem lies elsewhere. Assuming you don't have some kind of bizarre intake manifold, I suspect the cold start problem is either due to a vacuum leak(s), or it is choke related. After pumping the gas 6 to 7 times the engine should try to start without the need for manual priming.

The problem with fuel leaking past the float valve(s) is being caused by either dirt in the system or excess fuel pressure. The maximum for most US made carbs. is around 7 to 7 1/2 PSI. If your fuel pump doesn't exceed this pressure there's no need for a regulator. Good luck...Al English
