As I was working over Xmas, my break before Xmas was spent with family, so didn't get to fly again. I got home last night, so today it was off to the field.

There was a 25kmh cross wind blowing straight out and it was gusty and very bumpy. During the last flight before Xmas, the engine hiccupped once or twice in verticals, so I thought it might be a bit rich still. Before any adjustments, I thought I would see how it went first, so didn't make any adjustments before the first flight.
No hiccups during the first flight and the transition was excellent. I've been running the idle speed a bit higher than normal, just until I'm confident that all is good and the engine won't quit. Well, that time has arrived. Another 5 flights with everything set as I would normally fly. No issues at all. Steady, reliable idle, smooth transition and no hiccups. It's getting better each flight.
After landing , the engine temp is measuring around 45 deg C. The main needle is open 1 turn and 2 clicks. It may still be a bit rich, but as it's running so sweet, I'll leave it alone.
I also checked fuel consumption after the last flight today. It used around 240ml compared to around 230ml for my 185's. P19 does take longer to fly than P17, so fuel consumption seems about the same.

I'm using the APC 21.5 x 10.5 PNC, but have another couple to try sometime - APC 21 x 10 WPNC and 20.5 x 10.5 WPNC.
