1987 140 vro idle mix screw help

[dsen]

I am tying to find out if the carbs on this motor have idle mixture screws and what is the best method to adjust them.

Boat runs a little rough when idling in gear. When I throttle up and clear it will idle in gear ok for a bit and the start to run like it is loading up. It stays running but doesn't sound smooth.

Thanks for any help on this.

The carbs have fixed jets in them. No adjustments. The carbs and the recirt system on the mtr may need some work.

no. What do you sugest on the carbs? Just have someone rebuild them?

Have someone do them or else get a factory service manual and do them yourself.
