YS 140 problem

[Bob Kane]

Do the fuel and pressure lines both connect to the
front of the engine on top of the regulator? If so, it
is the Sport. If the pressure tap are on the bottom
rear of the backplate, it is an L or FZ. 

You are getting excellent power. . .   is the engine
hard-mounted or in a stand?
