yamaha 25 two stroke running on 1cyl

[Av8erdunn]

Well I got the pilot screw put in an she idles perfectly. Right now I have both pilot screws on the carbs backed out 1-1/4 turns from a light seat. Before cyl 2 carb was backed out 4 turns and I am thinking that was too much. So know the question is, how do I set / tune the carbs now I have it idling good?

Anyone have an idea on this?

carbs that have the EPA cap have no spec.

I typically use the spec for pre EPA.

on yours if its a twin carb 25 would be 2 turns +or- 3/4.

Alright so I set it for two turns and she shouldn't be too lean or rich?
