134 F engine starting problem

I have been working on trying to get the 134 engine to run in my jeep. I have tried 2 different carburators, replaced the components in the distributer and the distributer shaft itself with a used one from a running 134 and believe that i have them set correctly and i have new plugs that are getting spark. I have tried adjusting the timing and i cant get it to run. The best that i get is an occasional backfire. The old distributer required upward pressure on the shaft itself in order for it to run. I am at a loss to what the problem is. Any suggestions would be appreciated.

Check in this order
1 firing order...ensure that the it is set up in relation to the direction of rotation and you don't have it 180 degrees off(#1 firing on the exhaust instead of compression stroke).
2 Insure it is getting fuel. visualy check to see if the acccelerator pump is squirting fuel.
3 Compression. If the engine has been siting for a long time, the exhaust valves can become sticky,causing compression to become erratic.
Other things to look for...sheared distributor(oil pump)gear roll pin,broken timing gears,stuck rings.
