Jet sizing and Carb questions
I have a set of carbs in question that are on my Johnson 40hp. I installed boyesen reeds with the recommendation of re-jetting. Took carbs apart and checked jet sizes.
My results: fixed idle jet #32
High speed #59D
This is on a big bore, not stock for the 40hp, 1.5 inch throat carb.
Stock jetting for the johnson 40hp has a high speed #39 I believe
I did some researching and the closest stock set up i can find to this (32 and 59d) is a 1979 70hp Johnson that stock was (32 and 57d)
My question is, are my carbs set up ok with the current jet sizes? I have no issues keeping the plugs wet, so thats good. I plan on shaving an undecided amount from the head to raise compression to around 160 or so, and was planning on getting some 56D jets from some reading I have done to "wake up" my motor, but 59d is larger than 56d so I think I am going to stick with the 59d but am unsure how the idle jet should be sized since this is not even close to the stock carb and jetting set up for a 1984 Johnson 40hp.
Any help and/or insight will be greatly appreciated as I am self learned when it comes to modifying motors.
