Finished constructing the new duct today.
Still need to make it Pretty but the fabrication is completed. To help the
fiberglass set to the cowl opening, I placed it on the radiator and fired up the
engine. After warm-up I goosed it to wide open throttle and achieved 6200
rpm static - need to reprogram the upper end of the EC2 as I ran out of mixture
as I hit 6200. So I think there may be a couple more RPM in the engine as
it continues to break-in.
If breaking it in using synthetic oil rather than
the traditional mineral oil is causing any problem the engine doesn't appear to
know it yet.
So - very please with that development and
will be glad to install the new duct "permanently" tomorrow and go
flying.
