j, pull the distributor cap and give the rotor a twist. It should move abot 15 degrees smoothly and spring back nicely. If not it needs a lube and possibly a cleaning.
Next double check for spark plug wire firing order just to be sure.
The timing should be checked at idle speed in or out of gear doesn't matter as it just needs to be set at idle speed. And by revving the engine you can confirm the centrifugal advance is functioning.
RE the carb, with a fuel bowl full look down the throat of the carb and give the throttle (engine not running) a twist. When you do you should see a small squirt of gas. This will confirm the acceleration pump.
One other possibility is carbon tracks in the dist cap. These tracks can be seen with careful inspection and tracks could cause this very problem. The tracks will offer a path of less resistance (due to compression) to the wrong cylinder.
Get back after these checks.
