OK, here is my problem. My Clark will not start. It was running fine, but after sitting outside exposed to last winter, it has not started since.
The information I have gathered is the following:
Clark C300-40
Propane Fuel
4 Cyl Engine
I believe the serial # is one of these?
356 1 5146
2372878
3275 24 188 24
Once I started diagnosing it, I quickly found coolant pouring out of the carb! Since then, I have replaced the following:
New Impco Model J Regulator
New Spark Plugs
New Plug Wires
New Cap & Rotor
New Battery
New Starter
I also took the carb off and cleaned it out, as it was caked full of "Gunk"
I have great spark, but it seems that the propane is not getting into the engine. Engine cranks fine, but it won't even sputter.
I know nothing about forklifts, just going by what I see. I desperately need help, and I found this great website with the hopes that someone can help me.
I appreciate any insight that anyone can give me because I am lost! If you need any additional information,. I will do my best to provide that.

I think you have your coolant lines in hooked up to the wrong locations on the regulator
the coolant passages in the reg are cast into the reg and is no way it could get into the reg unless the casting was compromised in some way, there is no gasketing for the coolant passages in a model J IMPCO Regulator just the fittings that screw into each end of it for the hoses.
The reg gasketing could have rotted out
If coolant was flowing from the regulator to the carb either the hoses were installed in the wrong place or the regulator froze during the winter and cracked the casting and let coolant into gas side of the regulator,if the reg did freeze then whats to say the engine block also froze?
Check fuel lockoff and try starting with ether and see if it will pop or start Did yoU replace the diaphragm in the carb or just clean it?
Thank you to everyone who responded. I should have clarified that the coolant was coming from the regulator. The head and block are fine, and compression is good. The reg has coolant that flows through it as well, and something inside let loose and was letting coolant flow to the carb.
Coolant out of the carb. sounds like a cracked head or block. If the bock is broken, its probably not worth fixing, if the head is cracked, then its worth repairing. After you determine if there is an engine crack, check the compression. The old 4 cyl. continental motors can run well w/ only 90psi.
I've never seen it, but maybe by fluke you only have a blown head gasket causing the problem. Good luck.

I agree with Kevin, no matter how many parts you replace you must first determine if engine is in good internal condition or if that is where problem lies. If coolant was coming out of carb it could have been someone hooked up lp hose to coolant port on regulator and is not plumbed correctly and is pumping coolant instead of fuel.
Also if "coolant was pouring out of the carb" this would be a good indication of something very wrong with the block/head.
Do a compression test of all 4 cylinders and see what they are.
If truck was outside last winter,was the coolant protection good enough to keep it from freezing? Is there coolant in the crankcase oil? Block/head cracked??
Check the vaccum line going to lock off in the fuel system. Sounds like it is not getting a vaccum signal.
Hope this helps
