Motion Pro Carburetor D Screw Adapter

thingiverse

I designed this conversion to switch the flat head motion pro carburetor adjuster to a D screw style. It fits perfectly on Motion Pro's Flat Head motorcycle carburetor tool. With this conversion, you can turn your flat head into a 1/4 hex drive for reaching small adjustment screws with any attachment of your choice. The design isn't perfect by any means, but it works well enough. I would recommend printing two or three copies of this conversion to ensure they don't become brittle from engine heat when making adjustments. I created mine using an Ender 3 Pro printer with Dynamic Quality set to .16 in Cura and printed it with a brim only on the edges.
