Johnson 3.5 hp needle settings

[FDenny]

Took carb off 3.5 Johnson JH -23H and cleaned. Did not keep track of how many turns the high and low speed needles were initially set. What should the be initially set at. Noticed that with the plastic knobs installed you only have 1/4 to1/2 turn adjustment because of stoppers

3/4 and 1 turn out high and low respectively Should get ya going. Adjust from there.
It’s a 3hp from ‘68.

Low Speed 1 1/2 turns out from lightly seated. Hi Speed, one turn out. Knobs are not installed until after Best settings are done. They are limited in rotation for good reason
