I need help with an inverted Webra .61. It is in a Venus, today was to be the maiden flight. I couldn't get it to run with any reliability. If I could get it running full throttle, it ran well there. Idle acted rich coming down from full throttle, seemed to go lean then die. Fuel was dripping out from the carb due to siphon effect. When I turned the plane upside down, the engine started and ran great. I have an inverted ST in my 4* and it runs great. The Venus has a rather high fuel tank in relation to the carb. Any help out there? I am almost ready to order a YS63 for this.
Thanks for the help, Mike
