Need help with 574 C 200 engine

So my neighbor has a 574 that has had a rough life. He got a rebuilt distributor and after he put it on it would not start. We drug it to my place and I found a few things. But it still runs rough and does not start up right away. It will cough and backfire. Things I found so far, Distributor was 180 off, points were not even opening, intake manifold gasket was blown out, valve lash was about .065, old bad gas in the tank. Some time in the past he has had trouble with it burning the points. Also the bushings in the distributor were worn. It has a riser on it to run the tach cable. The worm that drives the tach cable is missing. When I put my timing light on it the spark seams to be all over the place. I don't have a service book for a C-200 engine. Has anyone got the spec's for these. Like points gap, plug gap, valve lash adjustment and timing. I have it hooked up to a small gas tank with fresh gas, I have replace the points with the correct ones and set them at .022, I have replaced the condenser with a new one, replaced intake manifold gasket, adjusted valves to .014 cold, replaced the plugs and gaped them at .035. Also this model should have an anti dieseling solenoid. The coil is still there, but the needle is gone. I am sure I have over looked somethings. Would like to learn from some one else's experience!
 
Spark all over the place is an indicator of loose distributor bushings. If the timing (with the new rebuilt distributor is all over the place, it may be a non rebuilt distributor!!! Jim
 
check to make sure jet orfice is still in solenoid shut off meters fuel in carb had one missing in customer tractor acted like choke was on if someone had installed a new shut off solenoid that orfice jet has to transferred from old solenoid it does not come in new solenoid found that out the hard way
 
So Leemn, I did check to see if the orfice was still in the carb but did not know there was one in solenoid. So does the needle just stop all fuel but a separate orfice in solenoid meters the fuel?
 
I think the bushings are loose too. But what causes them to go bad so fast? it has a poor design for the drive and I wish it could be changed to the industrial version.
