Hey, Dave,
I think that you are probably in luck! Fortunately for you, there is a fellow about an hours drive away, who if he doesn&#039;t have a used engine he can probably reman yours. Call Landis Zimmerman, he lives at 1450 Diamond Station Road, in Ephrata, PA. Phone# 717-738-2573. As to your question of replacement engines, Hercules model IXK-3, or IXA will fit, and are almost identical, but neither of them have the displacement or horsepower of the IXB. Your best bet is to stick with the IXB, in your OC-3.
