This is weird. I finally put another bike together with the new style NT carb. The engine is a Skyfire 66cc with about 50+ miles on it. The bike runs pretty well but for some reason when I rev the engine it will start puttering. It revs up but then it takes at least 2 seconds for it to rev back down to its normal idle.
Any ideas what could be causing this?
