What rod did you get for it, an OPS one?
Are you tapping the backplate for pressure?
Not sure on the rod - Bill just said "I have a good rod for it" and he said what from but forget. Rossi or another Rossi clone? Others would know more about this, but as I understand it there were several 2.5cc engines through the '70's and '80's that had interchangeable internals, I guess this is the "Rossi clone" crowd.
