Check all ign components. Good spark is key, a weak spark won't fire with propane. If you do need to replace any fuel parts all the impco stuff is fairly cheap. I replaced my whole fuel lock that had a bad diaphragm for abit more than a rebuild kit.

Recently i had a weak coil on mine that caused it to run poorly and eventually die completely.

Tune it by adjusting the timing.

There is plenty of info online. Do a quick search to find the components and likely causes. Propane is very simple.

I would conform you don’t have a obstruction in the intake.

Assuming you checked all the easy things first.

I bought it about 2 years ago, was running ok then, but was really hacked up.
It spent well over a year in the shop and i fixed the coolant lines to the propane system, hydraulic issues, wiring, rebuilt the kinpins, new exhaust, tore out the rotting gas tank, new tires, etc.

It has a new filter, though the whole setup is sort of fab'd up. When i bought it, there was no filter or even pipe connecting the filter can to the carb (or whatever the carb thing is called)

I used dust collector hose to attach it as the factory hose has been NLA 30+ years.

If it's an impco mixer, there is good troubleshooting documentation out there.

Tuning a propane forklift?

I have a 60s Yale 5k forklift. 6 cylinder Chrysler industrial flathead engine.

Was gasoline, but at some point many years ago, it was converted to propane.

It runs, but wont stay running at idle, have to keep it rev'd up a bit.
Seems way rich, like get black smoke, chugging and propane smell out the exhaust.

Im not too familiar with all the components. Is this something that is adjustable, or something beeds replacing perhaps?
