Re: 4 cylinder wisconsin propane

Tim boyd · May 13, 2022

Hello everyone, it's been awhile since I have some help on a project. I recently bought a snorkel man lift with a 4 cylinder wisconsin motor, basically I bought it sight unseen. The problem is its propane and I have no clue, it has sat for roughly 7 years. I managed to get it to turn over and I have spark but it doesn't even try to fire,I cannot find any selonid in the fuel line from the tank to the carburetor and doesn't appear anything is missing.I can't seem to find anything on the Internet that is helpful. Could anyone please point me in the right direction. Tia

Propane systems work very well and are usually trouble free. They are not affected by sitting like gasoline systems are.

Something you can try, prime it with a shot of gas, see if it will fire.

They are a fairly simple system, most initiate the fuel flow by sensing engine vacuum, some have a solenoid valve, some have a primer button.

Trace the high pressure line from the tank to the regulator. Crack the line loose at the regulator, it should have some serious pressure there. Be careful, the vapor is extremely cold!

Try the shot of gas first, it might take off and run once it gets to producing some vacuum.

If you are trying to use a 20# grill tank, turn it upside down. Your grill uses vapor and the V4 should use liquid.

504 I'm thinking the new 20 pounders have a safety high flow valve, open it to fast it shuts down, turn it over it shuts down. Propane experts input needed.

I have been fooled by the safety valves. Definitely open em slow. Nothing like chasing your tail to fix a problem that isn't a problem!

You need a tank designed to allow liquid propane to be drawn off. Grill tanks only allow vapor to be drawn off. Modern grill tanks, even upside down wont work as the floats and safety valves wont permit it. I dont know for sure thats what you are trying to do, but if so, you will need to get the right type of tank like one designed for a forklift.

I am using a tank for a fork lift

Tim boyd · May 14, 2022

Yes I am using a forklift tank

Tim boyd · May 14, 2022

I was wondering if I could do that, I questioned that when I seen a vacuum line coming off the bottom of the carb

I am not an expert,but I do a little bit of LP work. I went through 58 tanks Friday(slow day)

My large forklift has a valve that senses vacuum and lets the Propane in to the carb. No wiring; all automatic.

I see you are using a forklift tank. Great.
BUT be sure it is in the proper position. there should be some sort of indicators
on the end of the tank near the valves to show how to position it.
A guy I know had a forklift that wouldn't run well. It idled, no power, just barely
drive. I happened to look, and found to tank was out of position, and it was drawing
vapor, not liquid. I turned the tank, so it was drawing liquid, and away he went,
problem solved.
