I just took my 54 out on it's first trip around the block sinse getting it. It has a 4speed tranny. Reverse works fine, It moves through all the gears just fine. After taking off in 2nd gear, it does just fine, but when i go to third it falls on its face and wants to die, acting as if the engine speed is not high enough, but that is not the problem. Is it some kind of transmission problem or does it have to do with the carb. or some other engine problem?
Thanks,

It's possible the torque of the engine just isn't up to the load you're putting on it, but if that's the case, there's something seriously wrong that's limiting the engine's power. It should accelerate in third gear smoothly from about 15-20 MPH or more.

With my SM420, I used 3rd a lot for city driving. I wore out one third gear and now a second is starting to sing. I suspect the shaft and bearings are worn. All the other gears worked fine and were generally quiet.
