Folks recently rebuilt my carb on 1964 Ford 2000 4 cyl gas tractor and now need to dial it in. Got idle set no issues. Now the Ford shop manual says to bring engine up to operating temperature, remove any three spark plug wires, open the throttle to full throttle setting and adjust the main needle until highest operating rpm is obtained. Is that right and is it they simple? Just seems a bit odd to pull 3 sparkplug wires off and reave it up?
