If it seems tight, maybe it just needs more break in time? I had/have an old worn out .19 that did that too. It would just cut out at full throttle. Never did figure that one out. I was going to play with shims and stuff, but did not think it was worth the effort. Yours is new though.

Being new would probably make it more sensitive at high speed . I would run a smaller prop for a while and see if that helps. Good luck with it.

If it has a cast iron piston then those Enyas often needed a lot of running in. It would be worth checking and replacing the conrod too if there was any wear at the end of the break in.

Hi!
Your engine has an iron piston /cylinder and as such need longer running in time (running rich with throttle drum fully open) than "modern" ABN/ABN/AAC engines.
It's also vital that you adjust the high speed needle a little rich the first 5-7 flights, holding the nose of the plane straight up when adjusting the engine. A minimum of 20% castor oil is good to use and some nitro (5-10%).

I would have to agree, more oil and caster. maybe a smaller prop for less load just for break-in.
