Speed surging, especially on low setting
Remove one screw on rear cover. Note wire colors coming from pcb at top of assy.
Replace electronic speed control pcb. You will probably have to loosen the two screws holding the brass end plate assy to install new pcb.
Note the number of turns you loosen, so you get it back in the same position. Tighten locking nuts on screws.
