Anyone have any good tips for setting the mix on a propane carburetor? i have several forklifts a couple of which are hysters with the little 2.something out of a chevy nova with HEI ignition but i seem to always be fiddling with the them. I'm getting tired of it and wonder if theres a proper way to set the mix. I think the carbs are Impco but im not completely positive.

do you have the tool to set the mixer? made by Impco, if not you need that if anyone has had their fingers in the mixer. they are known for getting the solids out of the propane in them & gumming the moving parts up
you can get it where you get the rebuild kits at for them. it looks like a flat metal ruler with a few different notches on it with the corresponding part on it.

I get all my forklift parts from Parts R parts so i will talk to doug and have him get me one. Forklifts are a necessary evil around here and it seems like that evil goes through ALOT of propane lately...

Wants to try to run on either, but not on propane.
have you got voltage/ vacumn to the fuel shutoff?? I don't know which shutoff you have on that lift. has it backfired? was there a tear in the diaphragm when you got it apart? it would be nice if you could post a pic or give me the #s off the carb & mixer
Has adequate gas flow to the carb during cranking and if you apply vacuum via mity vac to the shut off but still wont fire. IT tries to run but just wont, Timing seems good. Vaporizer is doing its job and sending propane gas to the carb. carb guts were pretty gunky from the PCV but nothing horrible, diaphragm was a little dried out but not cracked or split and seemed to seal well using the finger compression method test. AKA you just squeeze it. its an impco 100 carb
