RE: 1.60 fx and perry pump ¿where to drill?
Devil,
Do a search in the Engine forums... I think I remember seeing a post there (maybe from Bax in the O.S. support forum?) that had all the information, maybe even a photo or two.
I have that engine in a Great Planes 25% Giles. Instead of using the pump, I used large diameter fuel tubing, clunk line and large clunk (and stock muffler). Runs great....
Good flying,
