I just ran the used 40 6002 on the bench to make sure it was ok. I installed a 0.294 (7,5mm) venturi and PA NVA.
The engine was leaking some fuel on the front bearing, but it turned a 12x6 as strong as my Enya 45 6001 Restored by F.Bowman to better then new. It would peak about 9900 rpms using the Enya Original Muffler, 7,5% Nitro 22% lube, and a old unknown plug.
RPM was not so steady at 8000rpm, it would fluctuate from 7850 to 8100. Above 8400rpm it was quite steady.
I am not sure how to rate the compression of this engine, because it has a Dykes rings, and I heard it is supposed to feel that it doesn't have any compression.
I will see if I can put it on the Pathfinder tomorrow and fly it.
