The timing is set to 35 degrees at 3000 rpm
It does not seem to be running hot.
It frees instantly.
It seem to be able to run at 50 mph for hours
I have been running on modern 2-stroke oil for outboard engines, as normal 2-sroke oil resulted in oil flowing out of the exhaust. (Have changed to normal 2-stroke oil now)
What made me think of the jet, was the backfiring.
