Less than ideal Carb Air Box repair
Posted: Sat Jun 14, 2025 2:14 am
Recent discussions an IA/A&P friend pointed out the repair on our carb air box was not a proper repair and that a rivet from that repair was missing. That rivet likely went into/thru the induction system and into the engine.
This mechanic mentioned how Air Box issues can cause partial or full loss of power by blocking the induction system.
We had not looked closely enough(most people don't) at the air box and no doubt ours in not usual. So look at yours closely checking for pivot bushing(fore/aft, up/down) wear, good sealing at the butterfly, proper hardware at the control arm/linkage connection.
