Hello all,

I am currently working on a 41′ MD-20, 1.5 HP single, and I have recently coil swapped this motor. Differently from the HD and larger TD, I believe there is a low speed air needle, but on the tank, there is no place for the dial to drop down into. The carb itself has a screwdriver-adjustable needle as well as the air needle, but beyond that, I have no idea.

If anyone has any experience with these, please let me know.

Aidan
