Things are a lot better than they were, but I still get really hot, really fast. There's a certain portion of takeoff, pretty much right when I take off, I will bust 420 pretty regularly, especially in this heat. Two flights ago, hit 441, but didn't even notice until I downloaded my savvy data. If I nose down, temps come down immediately, and they typically stay there the rest of the flight, regardless of climbs, etc.
I have retarded my timing to 23 BTDC, enriched the idle mixture, did some moderate work on the baffling, and it all made a significant difference to bring down my CHTs. Now that it's super hot at my home base in KSEE, I'm creeping into too hot territory again, even if it's a blip (12s at 441). Fuel flow is about 17GPH when the CHTs peak after takeoff.
I'm not asking for troubleshooting help here, as I'm going to redo my seals very soon, however, is it normal for the temps to go up as fast as they do on my plane? I read of some people getting hot 1000' or 2000' feet in, I'm super hot 100' above the runway.
