So I have installed a new carburetor and fuel lines and a fuel filter. Fires up instantly with electric start and idles great. Snappy throttle response but anything over half throttle and she dies; let off and the engine comes back to life. If I hold it open she will coast to a stall. The fuel filter has fuel in it when this is happening.

I've checked the ETON CDI and both restriction wires are cut. This is just annoying now...
