I have a 1939 A handstart that I bought this spring. It hadn't run for maybe 20 yrs but I got it going and used it a bit this summer. One thing I find odd is that sometimes it will run fine and the governor and throttle controls will work properly and then the next time I go to use it it will run but it seems like the throttle has very little effect on the engine rpms and it doesn't seem like the governor adjusts to changing load. It seems to me if this were just about wear the governor shouldn't work at all, but since it comes and goes might something internally be binding or sticking? Thanks,
Pete
