RE: Enya .60x Engine
I've got one the same as that except not pumped as that one seems to be. A brilliant engine, AAC construction (not ABC) and simply never seems to wear out. I use zero nitro in mine and get easy one flick starts. According to a chart I've got covering nearly all Enya models it's rated at 1.8HP (at unspecified revs) with a rev range of 2500-17,000.
