Just got a nice looking but used MTH 384E with PS-2. Model 10-1222-1 from 2004. Conventional works well. In command it starts well, but it slowly accelerates to runaway speed. This is with the remote speed at 2. I have checked the tach strip wheel and it is tight and the alignment of the tach reader is well centered over the wheel. Any other suggestions before I contact the seller.
