Have you checked the fuel lock solenoid or for test just bypass the valve go from the bottle to the vaporizer.
I have run out of ideas on the zenith carb. I also got a impcp ca100m-1 with the lift. Can I just drop that in place and just use the zenith vaporizer that is on it?
Yes, the Impco Ca100 is a propane mixer/throttle body. The vaporizer turns liquid propane into gas, the mixer/carb is the throttle control. Does the distributor still have points? Have you set the dwell? I have a 40 pound propane bottle with a hose and part of an old weed burner I can start any spark ignition engines to test.
You can get a hose that can feed the mixer from a BBQ or RV bottle maybe start from the mixer backwards to eliminate guessing.
It still has points. I checked them, but I will do it again and I will also replace the plugs before I try the impco.
Fixing old forks,I have noted that often the distributor is very worn on the shaft,and timing can vary widely,which is often a cause of no start,and if it runs ,no power......cure is a replacement electronic dizzy ....dont waste money with the car dizzy repairers,who charge hundreds,and stick a bit of epoxy in the bearings.....it wears out in a couple of weeks.
You gotta show us what the elusive side covers look like. How long does the engine run when you start it? It really sounds like the fuel lock is closing. The coil is not expensive 10-15 bucks maybe change it on principal. The other thing, IF it has a condenser in the distributor change that.
Actually ,thats pretty good for an old Bendix gear......its the flywheel that is often the problem.......well not the flywheel,but the ring gear....a four generally stops in one of two spots on the ring gear,teeth get chewed at these locations....Bendix spins wildly before engaging worn teeth,...the rest you know.
