Success!!!!! Of a sort... Today I annoyed the hell out of the neighbours by finally hitting full throttle.The engine really has some balls. The low end needle is unscrewed to it's limit and the engine coughs and stutters as the throttle is opened but before where it used to die it kept running.As there are no other mods to be made with the current setup next week I will get a new carby and hopefully it will behave itself well enough to be trusted in a plane.
