Looks like the temps are OK, but with an OAT of only 61F, a bit too soon to
know how it will respond to 85F+ days. I notice you are showing an Air/Fuel
ratio of 15:1 – just curious how you are measuring it and why that ratio
when a 12.56:1 produces best power and a ratio I would think you want for take
off.
Tough to spend that money on a redrive and
get no support – hopefully, the leak is minor and/or can be easily fixed.
Looking forward to more test/flight
results,
Ed

Subject: [FlyRotary] Engine run
Today I ran the engine .9 hour, .7th's static at 4700 rpm
- 13B, Marcotte 2 - l redrive
Water temp
235
OAT 61
Spring hasn't arrived above the 44th parallel
The static engine run temperatures climbed quite a bit with
the cowling on and working on the programming I didn't notice that this was
happening, but they went right down when I idled back.
I will have to pull the cowling in the morning and check the
redrive, it appears the seal is leaking on the flywheel side. With no
support from Marcotte, I may have too much 80w in the gearbox. I believe
that the temperatures look good for flight. JohnD
