Thanks, but no lever height adjustment or prop changes for me. Not that serious, and I normally prop for the performance not for engine tuning. I flew my new DLE-30 with the Cyberplate conversion tonight and it does the same thing, almost identical with Vess 19A. Great little engine, I have to say. I will probably try the vent line on this DLE-30 first because I will be checking the nuts and bolts and will have the cowl off anyway.

Won't be until after the weekend though, no flying for me for a few days.[] Will report when I do add the vent line.

Thanks again.
