I picked up a non running clark c500 y80 today I am unsure of the year the data plate was painted over at one point. I assume the serial # is y685-385-2153 then 273 appears to have been added at the end. Lift hasn't been run in 2 years but was apparently in fine running shaped when put away.
Either way there are a few problems I have found with the lift so far.
one is that fuel does not flow through the vaporizer. I already checked that electromagnetic safety valve, and even removed it from the system to be sure. I assume the vaporizer is bad or stuck or clogged? It appears to be newer compared to the rest of the parts.
the second is that it appears to have alot of coolant mixed in with the oil when I pulled the dip stick. I assumed this was a blown head gasket issue. So I pulled the plugs a few were quite damp. I did a compression test and got a result of from back to front 155,140,115,0,145,145. The cylinder with zero it appears the one of the valves is stuck open when cranking and looking in the spark plug hole it isn't moving.
I didnt plan on rebuilding the whole motor is there any known work around for this? I sprayed a bunch on penetrant down the cylinder to see if it loosens.
Also mice or something ate through two spark plug wires is there a delco or generic PN I can use for these?
Also what even is this motor? Its an lp flat 6

Yes I have 12v's to the solenoid, coming from an oil pressure sender fed off one of a remote filter flange. I am thinking the issue might not be with the vaporizer or shut off..
I pulled the intake tube off of the mixer/carb to see if it would run off of carb cleaner or starting fluid.... and a bunch of coolant came running out. I don't think that seems right and probably has something to do with my coolant fowled plugs.
Thanks so much for all your input so far.
The fuel system is as follows:( All Impco mixer (carb) - CA100, regulator/vaporizer (as installed- Model J ) & fuel shut off solnoid. If I were you I'd get the mixer diaphram, replace the Model J with a model "Cobra" & replace the electric solnoid.
They've cheapened up the Model J - I have all sorts of problems with them now- the Cobra looks & mounts the same as the J but internally it's updated to a newer design.
Once the new parts are installed, trace the wiring to the solnoid- it should go either to the ign coil or to a round silver device hooked to the intake manifold. Either way- you should see 12V at the solnoid while cranking.
The system works as follows: the mixer senses a vacuum while cranking- the vacuum signal is sent to the regulator thru the fuel feed line which opens the ports in the regulator which in turn starts to let fuel flow to the mixer. The electric solnoid is a safety feature which stops fuel flow when the ignition is off. If equiped- the round silver device shuts off current to the solnoid if no intake manifold vacuum is present- regardless of ign switch possition.
thanks for those p/n's. I did have that fuel line and everything in place when cranking. Only pulled it off as a last ditch effort to see if fuel would pass through the regulator on its own. At the time I didn't realize it was pulled through via vacuum. Any idea what carb/mixer this might be? I will order a diaphragm/rebuild kit for it.
F227 engine

Wires are Delco 446-EB
That has a common type Impco fuel system. You shouldn't have any trouble getting any parts for that forklift. The 2 linkage arms are needed to allow the governor to throttle back the carb at full rpm. You have to hook the hose up from the fuel regulator to the carb to allow the regulator to make the fuel start to flow when the engine is cranking.
Would this be a Continental F226 motor? I am having a hard time finding parts for it. If you have the pn for the cap and rotor that would be great as well. I cant seem to find any markings on the fuel mixer. Its crudded up to all **** I am sure they're there some where.
Imageshere is the fuel mixer.
I am unsure of what that secondary linkage arm is doing. it doesn't seem to be connected to anything but a tension spring up by the radiator. It doesn't really move much when the throttle peddle is pushed.
I would love for those part numbers and actual year if you could BBforks. That would help tremendously. I read after making the post that the water in the oil isnt usually due to a headgasket. I just assumed and jumped to the compression testor. Which was good or id never have saw that valve..
So I guess my next question would be is how do I get the mixer to pull a vacuum? Ive been cranking the motor all afternoon and have yet to smell a hint of lp.
Kevin this message boards is kind of anti pictures they dont use bb code like most others. You actually have to write out the html
mrfixit yes I did drag the lift home with that van. My bhole was puckered the whole time. I pulled it up on the trailer out of loose sand with the forks dragging with a 12k winch that was barely doing it. The trailer was fine. The truck on the other hand... way to under powered I only had maybe a 9-10mile trip never went over 40. Had the brake controller maxed out on the trailer too.
Makes me miss my old 7.3 f250 that thing would pull anything.
My question is, did you pull that forklift and trailer with the white van? How did that go? :-)
This is the first post I have seen with pictures in it,I have to ask how is it you embedded these pictures into our post........and the 273 on your data tag is more than likely the year it was made feb. 1973
I'll look up the year & post- as far as the regulator not passing fuel- the regulator needs to feel a vacuum from the mixer (curburator) before it will pass fuel. The engine is a Continental- used on millions of lifts- good reliable industrial engine. The sticking valve surprises me- I've never seen that- even on engines that have sat.
It should have a Delco distributor installed- parts for it are available at NAPA- I'll look up the part #'s if you need. The engine oil looking like a milkshake is probably from condensation buildup from the engine constantly being started, run for a few minutes, then shut off. The key to look for is- is the oil overfull? If not, replace the engine oil & filter, run the engine till hot, shut off & replace the engine oil & filter again. Depending on how loaded up the engine is, you may have to do this numerous times to get the sludge out.
one more of whats left of the data plate. I dont know if there is a way to deduct the year or anyother info from the serial #

Okay update the wd40 worked faster than anticipated. it looks like all the valves are moving now, and compression on that cyl went from 0 to 135. A little low but it hasn't run in a while. Here are some photos of my lift truck.

From the vaporizer it goes right to the carb via a large rubber hose. The safety switch is off here but in the background.
over all shot of the motor.
