Thats a wow add-on factor there BRO, just dump the Roto carb and the make sure its all roto start. the slide is far better although as said b$, not the ideal candidate for off road. But in saying that, I intend on getting my new engine without a roto carb and am going fro the slide version, some on this post also have a slide carb with their engine upgrade...personal pref..? But wow, nice engine there
