Next is the recirculate function doors and actuators. For the most part there are dimples from the factory where you need to drill. The only place there aren't is for the cowl actuator mounting points, so that one takes a little bit of work. The assembly manual gives some dimensions for help.
I used a carb return spring for the cowl flap. I think the parts are being re-popped now. I found these parts used a while back before they were available.
I drilled that cowl inside pivot point from the interior side. The dimple is pressed from the cowl side but I wasn't even going to try that. Drilling from the interior was the obvious choice.
