Default Info about this YS please

I picked up a old Sig Mustang 450 and it had this motor with a tuned pipe. The side says YS 45 FS the other side says Made In Japan. The carb is really weird in that you can not see a rotating barrel. The 2 nipples went to the fuel tank, I think and I have no idea what that screw is on the bottom. Any info would help and any guess as to the value would also be appreciated. The piston and sleeve look like it was run very little if at all.

Thanks

The two fuel nipples run to the fuel tank. One is a pressure feed to the tand the other is fuel to the engine. The "screw on the bottom" is a fuel pressure regulator. The fuel is under pressure (tank is pressurized by the engine) so tank location can be most anywhere in the airframe, usually on the CG of the plane. These engines while a bit different to tune but are sweet to operate once you figure them out. Here are a couple links that might help you out.
