I pulled the cowling today and inspected the FWF area. Not the first time I've done this but I was being very thorough. Found a couple of minor issues:
1. Slightly loose bolts (castle nut style) on throttle and mixture cable rod ends. Tightened these until snug and put in new cotter pins. I reversed the mixture cable bolt and used a shorter one because there was slight wear on the lower cowling from rubbing at full rich mixture setting.
2. Broken L-bracket for the sniffle line. This bracket clamps to the exhaust using a stainless hose clamp, with an Adel clamp holding the sniffle line. Looks like heat and flexing broke it at the bend.
I fabricated a new one using .018 stainless steel. Hopefully this will be more durable.
