RE: DL-50 engine
Something like this?
1 TDC
2 Set set scale to zero
3 Rotate crankshaft counter clockwise until spark
4 Adjust timing until you spark at 28 degrees
5 Lock down the hal sensor
W8ye, I am not sure I understand this statement and how it translates into the degrees that one should set the timing.
(If you slowly crank the prop around, the ignition will fire at the full advanced position. )
