Been in the process of restoring a 50 for a few years. Engine has been overhauled. Bored block 90 over, new pistons, rings and the head has been rebuilt. Rebuilt carb and distributor. Got it running over the weekend, fires up on second round. Run strong under load but if it's running free it hunts for an idle. Fast or slow idle don't matter. Pull choke and can make it come out of it. I've had the carb off three times and cleaned. Readjusted valves and checked spark plug gaps. Tried adjusting carb but seem like nothing changes. I've sprayed carb cleaner and blown through all ports of carb. Sure seems clean but I could be missing something. Any and all advise would be great full. Thanks in advance.
