May be you can help, The rear float bowls on Our 1250 Dominator seems to be draining out, car stalls after burn out, seems to just fade away and stall out. I have adjusted bowl level and you can clearly watch it drain out?? any ideas

Make sure your power valve does not leak.I had 2gaskets by mistake and it would run dry.

What is your fuel pressure? For float setting I just set it so the gas is just at the bottom of the hole, not running out. Also you could have fuel coming out of the vent tube causing it to flood out on sudden stop after the burn out. A fix for that is to use a piece of rubber hose raised up front to back with a air notch at the top for vent, I've also seen guy's use 90 degree spark plug boots.

6 1/2 like I said I can turn pump on bowl fills up turn pump off and it drains back.

I do also and it was the gasket causing the leak so what I am saying is check the gasket.

I suggest taking the carb off and test it on the bench by filling it through the everflow tube and you can watch better where the fuel is leaking.

I would say its the PV plug gasket also... its right
near the bottom so if its leaking it would leak MOST
of the bowl empty

I have fixed several where the owner didn't have the gasket seated properly on the plug and it would drain the bowl quickly. Also ran way too rich .Keith
