OK guys, I just finished the throttle and choke linkages on the Edge/DA50 and below are some photos. The lever that I added to the choke lever is made from a Hitec servo arm. I drilled and tapped the choke shaft to a 2-56 thread the way DA/Walbro does it on the throttle shaft. There was no grinding the old lever off as you can see. I used the old choke lever to help lock the Hitec arm in place. It worked out very well if I do say so myself sm=tongue.gif] ! The push rods move very smoothly with no binding and as you can see they are aligned very well without excessive angles to the carburetor attachment points. I do have a few other photos or if anyone would like a specific photo just let me know.

Monte, The pushrods are 4-40 and all the ball links are attached with 4-40 screws. The only thing that is 2-56 is the ball that came with the Sullivan "Locking Sleeve Ball Joint" but they sell a 4-40. If I can find one locally I may change to the 4-40 but for a throttle linkage I think the 2-56 will be fine. Do any of you feel the 2-56 stud on the Sullivan "Locking Sleeve Ball Joint" is not good enough?
