I've run UAV Bully engines for years (I still have another new 1.45) which were basically Webra engines with a 2-plug head and I believe UAV carbs and pumps. The engines always ran flawlessly for me. I wonder if putting an old Bully pump/carb on a Webra would work?? I do own 2 Webra 1.45s, but I've never run them. I hope they continue to be available here in the US.
