I have a Clark C300/40 forklift. The fork lift serial number is 356-37-4370. The engine is a Continental F163 LP. It will not idle. Process to start engine:
Apply full choke, start engine
Immediately move choke to 1/3-1/2 position, engine will idle fine
Once engine warm remove choke
Engine idles fine for ~10seconds, then will pop once (like a lean condition)
Smooths out and runs for a couple seconds then pops again
Repeats a few more times and then engine stops
I have cleaned the carb, it was very dirty. I have adjusted idle mixture screw but this has not solved the problem. Engine idle stop screw is adjusted for idle rpm. High speed operation is fine, but it does smell rich though.
Does the regulator need to be cleaned? The idle mixture screw is set between 3 and 4 turns out.
Thanks,

I would also check to be SURE the "tuneup" was done correctly and a full "tuneup", not just replace the spark plugs. You need to have new and gapped spark plugs (ask the guy changing them what he gapped them to) sparkplug and coil wires, distributor cap, point and capacitor and rotor button replaced. Make sure the capacitor is tightened down properly and the distributor and coil case well grounded to the frame of the truck.
AND timed with a timing light....
Edward,
Thanks for the insight. I will check compression.
it indicates not enough vacuum -pulling- enough fuel into the manifold,
not that the carb is not getting enough fuel. it may also be as simple as the idle stop screw if the missing is only at idle.
Valves were adjusted. I was wondering why reference electrical, valves, compression when adding a little choke and it idles just fine. Doesn't this indicate not enough fuel is getting to carb during idle?
Rick
adjust the valves too...and a compression test....
Thanks for the quick response.
Yes it has ignition points, a tuneup was done recently. I will re-check condition of points and gap.
I will check on the regulatory brand and location and report back.
Is there a test that can be performed to determine if it is the regulator?
Rick
Does that motor have ignition points? Did you check them? What kind of LPG regulator does it have? J&S type that is installed in the thermostat housing? If so, you would just replace it with a new one if that's the problem.
