Question about carb rebuild - pilot screw

Postby Fulcrum » Sun Mar 24, 2013 6:57 pm



When I disassembled my first carb, I screwed in the pilot jet to its stop before removing. It rotated 4 full turns. Now as I read reassembly instructions it recommends 1-1/4 turns out. I am reusing the original pilot screw and am curious where to set it. Thanks

80-81 carbs are 1.25 turns.
82-83 are three turns out from lightly seated.

Always helpful, thanks Steve. #2 carb was 5 turns out. Wonder why the PO had them so far out.

Only reason I'm helpfull is that 1982 GL carb rebuilding is still quite fresh in my mind! :lol:

Carb "adjustments" like that are trying to compensate for clogged jets or passages.

I'm so glad you asked this question, I had never read the pilot jets (idle jets right?) were supposed to be a few turns out... I have my screwed all the way in... I need to take my carbs off due to previous rust in my tank... What about the main jets, should they be a certain amount of turns out as well?

Also, I am running a set of 82 carbs on an 81 should I set the pilot jets 3 turns out per the above instruction?

Bob88 the pilot and idle jets are different. This pic really help. Here is a helpful link also thanks to SteveB123, who is the best by the way, that really helped me. The amount of turn out should depend on the year carbs you have installed. Good luck buddy.

the recommendation for 1980-81 carbs of 1.25 turns out is just a starting point before adjustment while running. Honda specification.
