Does anyone know what size tap the air adjustment hole threads are so that I can re-thread it? It`s the one on the bottom of the carb by the bowl. It`s # 32 on the parts diagram.
Thanks

 

Did the screw break off/ adjuster head distorted?

 

I had trouble getting it out but I finally did and now I just want to clean up the threads for the new air screw.

 

As long as you didn't break the fine tip on the adjuster in the carb body it can be replaced. The threads will be metric(don't know the size) but probably around a 4mm fine threads. Best to have a metric pitch gauge(in any metric tap set) to get the right thread pitch.

 

In case anybody wants to know the tap size is M6x0.50. I got one from MSC Industrial Supply in Pa. Worked perfectly.

 

Thanx for posting! I only missed it by 2 mm's!!
