Completed some baffling support around the oil cooler, riveted in place. Installed the airbox mounting plate, and safety wired the bolts. Installed the airbox, and checked operation of the carb heat. Installed the cowling... It seems the carb heat control arm is touching the inner cowling. I will need to do some adjusting to get the required clearance.
Fabricated the hinge pin hold downs for the cowling.
