Welcome back, Bill!
My my recent Enya lot included 3 .15-IV's. Ones reasonably used, one has a few tanks through it maybe (missing the carb sadly), and the last one is new. It's sad the carb for the one costs more than I paid for the engine and shipping. The new carb is about $30 shipped.
I'll be running my 120-4C today, burn the cobwebs off of her before storing for the winter. Man does she like to drink fuel....
