Harman P38 Comb Blower Voltage

[gfreek]

Does anyone know if on a Harman P38+, 2 knob, does the voltage to the combustion blower vary from 100 to 120V when adjusting the feed rate, lower knob ?? That's what happening and the comb blower is noisy around 110V..

None of the Harman owners had an answer??

Edit: You might want to PM member Don2222 - he appears to have a new combustion motor that improves performance. He might have reference voltage #s and suggestions for a fix...
