Carbs rebuilt, fast idle. '95 120hp

[Dave K.]

Hi all,
Had the carbs rebuilt w/ a noticeable difference. Problem is the idle is around 1800rpms. It does come down to around 900 when i slow the boat down sort of forcing the rpms down otherwise it stays at a fast idle.
I belive they're called Air mixture screws, one on each carb? Could this be an adjustment?
Any help is appreciated
Dave

Might try adjusting the idle speed screw. The red arrow is pointing at the idle speed adjustment screw. There is a lock nut that you have to loosen to adjust and tighten up when done to keep from vibrating loose.

Try the link and sync as the timing has a major effect on the idle speed as well.
