RE: Factory settings for an OS 40 FP??
Well I do have a twin plug Merco .49 that I haven't ran yet, for a vintage project.
And I do like the Irvines. To bad they are no longer made (in England).
(4) .36
(1) .40
(1) .45
(3) .53
I guess I like the Irvines a lot. Maybe the best sport motors ever made.
