We picked up this lift about 6 months ago, had a new model J regulator and CA100 mixer I put on, it would start and idle okay, but it smelled very rich but needed choked to run anything over idle, if you didn't choke it and gave it throttle it would just fall on its face and die. Even running choked the engine didn't have much power, it is a f245 continental. since then it has new LP hoses and I installed another mixer and a newer cobra regulator/vaporizer. as well as a new lock off valve and new propane tank. Still smells rich but needs choked to run anything over idle, even at idle it helps to have the intake almost completely covered. I did set the valves, checked compression, all the holes were 110-135. valves all moving. Any help would be appreciated.

Do you have the main fuel valve set to R ? If so, check the number on the diaphragm in the mixer. I see they come in lean and rich types.
Ok I thought I had put a new cap and rotor on but I had not, Runs much better, no miss. but it still wants a little choke to rev much over idle, without choke it coughs and sputters still.
It has new points cap and rotor plugs and wires, I have moved the timing advance and **** while running until it seemed to run best. I'll see what I can do about the miss. Thanks guys
Stam is right, also check the timing.
Get that miss sorted. Tune up parts are so cheap just put all new plugs cap rotor wires points if still equipped and coil!!!
I have tried richening it, leaning it, nothing seems to help it.
I cant say it doesn't have a vacuum leak but I highly doubt it, I have a good vacuum at the manifold, more than 40" water gauge cranking it over. That is between the engine and carb, on the manifold.
I put all new hoses on it as well and have leak checked them. no leaks.
I have tried spraying ether around all the gasket surfaces on the intake to see if it would get any into the engine, it didn't.
If you checked and have good compression on all cylinders maybe you have a vacuum leak. Did you adjust the mixer fuel valve richer? The one near where the hose attaches. Also is the hose ok that goes from vaporizer to mixer?
It has an up draft manifold, updraft mixer. Yes I do have hot spark, I have spark at all 6 but when running have a miss on 5, I have compression on that cylinder so I wouldn't think the valves aren't sealing?
Like I said I did reset the valves, everything I could find on contenentals said.014 and.016, unless propane wants different?
Downdraft mixer mounted to updraft manifold? Maybe a spring change? Way out of left field.. but thought I would say it.
I'm not even close to right this is a 60 I didn't look.
Are you getting hot spark?
You need to check the valve adjustment. The continental was touchy with a Impco system. Impco depends on good vacuum draw from the engine to regulate fuel.
