Are you advancing the timing, left lever on steering column about 1/3 - 1/2 of its travel distance when driving? You need to advance the timing in order to get it to run properly. Also, as mentioned above, the GAV, (choke rod) needs to be opened some... each carb will be different, but a good starting point, after warmup is about 1/4 - 1/2 turn open.
