Bob - First thing I'd do is check the ignition timing. Sounds like maybe the ignition wires are connected wrong, or the distributor is way out of time. To check take the plugs out and lay the #1 plug on the block with it's wire connected. Now use your thumb to feel for pressure on the #1 plug opening as an assistant turns the crank (indicating #1 is coming up on compression stroke). Now turn on the ignition and continue to turn the crank while watching the timing mark for #1 TDC - you should get a spark almost exactly at TDC if it's timed/wired correctly. If not you've found the problem.

If the ignition checks out, THEN suspect a starting valve or manifold butterfly problem. Try cranking the motor a few seconds with the the starting lever in "start" position and the choke full on, then immediately pull a spark plug. If everything is working right the plug should be wet with, or at least smell of gas.

Good luck!
