RE: McCoy engines
Ran one of my Redhead .35s this afternoon. I will confess to a bit of bias aganst the engine, having used so many of it's competititors years ago but it fired up instantly and ran well. I must say that I think the (tapered) needle was easier to set than the (stock) Fox .35.
The light was poor for my inexpensive tach, but it got about 9800 0n an old 10-6 Tornado wood prop with 5% nitro, 28% castor.
I purchased this engine a few years ago and do not know it's history. It seems to have been run a bit but not abused. It has the offset plug but is pre- lightning bolt.
