[QUOTE="altfuel1991, post: 285751, member: 1211"] re you running a vacuum lockoff valve, if so where is the hose connected to vacuum? It should be connected to a ported vacuum source. This will provide a constant source of vacuum to keep the lockoff valve open. If it is connected to manifold vacuum at WOT there is zero vacuum and the lockoff will close and shut the fuel off. You should not have to adjust the power mixture if you have a real IMPCO 425 mixer. They are all flow tested and adjusted when manufactured. If the above is not a problem I would check for vacuum leaks and also check the vaporizer. You can test the output pressure at the test port. It should be 1-1/2 to 2 lbs. If you still can't find anything, give me a call and we can figure it out. Propane systems and repairs are what we do. And no you don't have to buy anything from me to get technical help.
