Clark CLIPPER:
Running and Lifting Problems

Hey,
I just purchased an ancient Clark Clipper in operating condition. But it does have a couple problems that I could use some direction on.
First, it starts and runs great. But today I took it across the lot and after a short while the power suddenly dropped and it ran like crap. If I wait a few minutes and restart, it runs good for a little while then bad again. I noticed that the propane lines have frost on them when this happens. So I think it's possible the line is freezing and preventing fuel delivery. What do you think? Any fix for this?
Secondly, the the tilt back of the forks works but doesn't hold. It tilts and then drifts back quickly forward when you let go of the lever. I don't see any leaking fluids. Possibly cylinder seals or maybe the valve itself. What do you think?
Thanks!

Larry

Tight valves could be a problem. However, you say the fuel lines are frosting. That is
an indication of a problem in the LPG fuel system. It sounds like the liquid LPG is not being converted to a vapor state so the engine can use it for fuel. I suggest you check the following:
1- Coolant level in radiator. Low coolant can cause the LPG vaporizer to frost over and restrict or stop the flow of fuel to the engine.
2- Check for a clear flow of coolant thru the vaporizer. On older units a lot of things can go wrong, a hose liner could come loose and stop the flow, scale buildup could stop the flow, a weak water pump could the the problem, etc.
3- Replace the vaporizer. A bad vaporizer can also freeze and prevent the engine from getting the fuel in the proper form.
These are things I've seen in the past that can cause the probelm you describe.
Hope this helps.

Check you valve clearances.
Tight valves are normally the cause for this problem in the continental engines.
