I only have one enya 4 strk Sheldons in CA had a sale and I got the 40 for $129 I was very surprised that it was open rocker arms
purrs like a cat very quiet only a exhaust stack (no muffler) still very quiet at and idle you can hear the valves no plane for it yet
finish is outstanding I also picked up a couple irvine 36 2 strks which AJ Colholic made diesel heads for, Sheldons must find these
I guess from the distributors that are unsold left-overs since they are out of production engines but great prices
