It was nicely cool during initial running in then after a few tanks the 600's fan hub started slipping.. Pulled the engine and re-seated the hub. To dog it down I pulled the carb and used a plastic handle in there to lock the crank (no crank locking tool)
Everythign was fine for a few tanks after than but then it started getting hotter than I like even with the needles right out at max settings. Then the hub started slipping again so I've had it all out.
The carb gasket was a little bit sooty with signs of leakage around one of the retaining bolts on the isolator. I cleaned it all up with spirit to see if I could re-use the gasket for tomorrow and it looked fine. But while tightening the carb back down I see the isolator starting to crack around that bolt.
I'm not going to speculate whether it was faulty or I over tightened.. academic .. and arguable without a torque wrench and just 'feel'.
I'm reporting this more as another thing to watch out for if you start getting the same signs.
The isolator isn't listed as a spare on the main sources .. so it'll have to be a call to FL where I got the engine to see if they can source one and a new gasket set.
I'm oversensistive to engines after recent events. IR gun temps were 135F max...but I don't trust that fully..it felt hotter than that to a finger.. as in 2 seconds and very uncomfortable

. I'll have to suffer and fly some of the other five..well it will be five when I've fixed up two that I dinged over the last week getting the inverted flying lower and tighter...not a trick I'd practice with the big money toys.
