'73 SA Fowler Mainliner

[ericmt406]

Does anybody have experience with these machines? Im having some trouble. Machine runs at about 125 in first through third gear no matter what the fine adjustment is set at. Fourth through seventh work just fine, maybe a little cold but fine for the most part. Arc Force seems to be working properly. Outlet works. Machine revs and idles as it should short of a little vibration under load (bearing?). Machine is new to me. I do not have maint. logs from PO. I have done no other trouble shooting. I would call Hybriweld but the numbers are disconnected, and the websites are down. I dont want to arbitrarily start replacing brushes or shunts. Any help would be greatly appreciated.

That was it, the knob was pointed the wrong way. I didn't do it, but I should've caught it sooner.
