Manual Choke Linkage--3mm-53

Here's what I came up with for a manual choke using around the shop materials:

One servo arm, any type will do, even round. A couple of threaded rods, one small ball link to avoid binding, two flat washers, one brass servo eyelet to fit the center of the servo arm after opening up the hole for the servo screw a little, a couple of 4-40 clevises, a 4-40 screw, and a 4-40 nylock nut. All you're doing is making a bellcrank to change the direction of the linkage 90 degrees. Works great.
