94 harley davidson sportster. I changed the head gasket yesterday now that same cylinder is misfiring?

Ive checked the compression and that cylinder matches the compression of the other cylinder but for some reason it still wont fire. Ive changed plugs and the spark is good across a spark plug tester so the ignition coil doesnt seem to be bad. I noticed that when i twist the throttle back a few times before i start it it will start and idle for a few seconds and then die. but if i sit there with the choke pulled out and put my hand over the exhaust for that cylinder it doesnt get hot like the other side. If by chance i swapped the pushrods while changing the head gasket would that cause the problem or would it cause the valve to crash into the piston and stop the engine before it would start
