3210BE01 should be a 1990 Wheel Horse 210H. If you go to Red Square (www.wheelhorseforum.com) you should be able to download a User Manual and Parts List, maybe a Service Manuel. You could post about you issue there, you'll get some help.
I have not worked on a 210H, but I have several 520H's. It sounds to me like you need to inspect your speed control linkage and re-adjust. Its tricky the first time, but the manuals will walk you through it.
