I've got a Saito 1.50 mounted inverted in a H9 Showtime. I've got it set up with an APC 17x4W on 30% heli fuel with a Perry oscilating pump due to the tank being mounted close to the CG. It runs flawlessley with a very dependable idle, good transition and a top end around 9200 rpm. It's got about 4 gallons of fuel through it and I've set the low end needle valve according to the manual. The problem that I can't seem to solve is the presence of large amounts of raw fuel on the firewall and exterior of the plane (top and bottom) after a flight. It's enough that it actually pools on the cylinder cooling fins, engine, mount top and bottom of the plane. In the attached picture the mount is noticibly wet with fuel. I've replace all of the tubing (in case there was a pin hole somewhere) and replaced the o-ring in the pump. The pump is also turned all the way down. I've tried running without the pump but fuel draw becomes an issue and the transition for idle to fuel speed falters. When it is running on the ground there is no noticible fuel spray from anywhere. I'm thinking that it's fuel spray coming out of the carb despite it having a stack and the fact that the fuel is EVERYWHERE afterwards not just around the exhaust. It actually builds up a pool along top edge of the firewall by the end of a flight. Never seen or experienced anything like it. HELP!?

Thanks in advance!
