I just discovered that the carb cam was severely out of adjustment. With that I now am at least close to full carb travel with the throttle cable.
This engine has no high or low speed adjustment needles, everything is fixed orifices. I was really confused because the air silencer has plugs and labels indicating slow speed adjustment, however they are not needle screws and do not adjust anything. And the manual indicates that they do not have them. So apparently it was a part used on fairly different engines.
I did find that the carbs and chokes were not synced properly anymore, that should help some.
So I think that I am slowly getting close. I suspect that the fuel pump diaphragm, or bulb check valve, may be leaking as the bulb never gets hard now. At first if I pumped the bulb it would get pretty firm, so I am assuming that is how it should be.
