Hi jez 33

I gave up on that engine and converted to electric with great results. I get almost 15 minute flights.
Let me tell you though, as mush as i like electrics, there prices really turn you down.

This is my thoughts on that carb
I think there carb should be fitted with a slide carb. Being able to control the carburator will make it run much better. Ever wonder why every manufacturer out there has either a slide or rotory carb on the car, plane, and heli engines. I mean light machines should ask themselves this. Does it make sence for you to open and close the exshaut to control engine rpm when the exshaust lets the engine breath.
