carb locks?

[67chevelle]

I was trying to turn the high and low adjuster on my 372 today and noticed they wouldnt turn.I didnt torque on it too hard cause Im thinking there is some kind of a lock that I've heard people talk about.I see there are limiters on both,but how does a guy get them to turn without fear of breakage?Thanks for any help-Kory

Kory, Pull the plastic limiters off.( grasp with pliers and pull straight out).Look carefully -one may need to come off first then the other. Set the carb and push the limiter caps back on. Only do this if you know how to set a carb.

Will the screws turn in either direction, or only in one?

The saw came out of the box with the low side all the way lean (clockwise) against the limiters and the high all the way rich against the limiters.

the initial setting is about one turn on each,if you are not satisfied the way saw runs,you can play with adjustment to get what you think is the best.But dont go too lean on HI speed adj.
