Al, I think Chuck's fix would've addressed if your startup problem was very short.
Yes, my unsafe solution involves shooting raw fuel... but, instead of carb cleaner or something like that, I shoot a slight amount of propane in... although if you have multiple trumpets, that'll be hard to do.
Propane is already a gas, so it mixes in well.
If your engine speeds up momentarily when you shoot it in, then you're not getting enough fuel.
