Flat spot in throttle
I have suddenly developed a flat spot or severe stutter at the bottom end of the throttle. If you slowly accelerate, there's no issues.
If you get on the throttle quickly, the flat spot / stutter shows itself. This just started out of nowhere.... See my sig for my setup. Any suggestions?

I'd start by taking the carb apart, and cleaning it, then inspecting it!

I wouldn't think it would be dirty since I just did the jet changes at the beginning of last summer, but I guess it's a start.
Does anyone know what the float level should be set to?

You changed the pilot jet? From what to what and what changes to machine from stock?
