I just got my new 1974 CB360 running today. It sounds like it idles nicely and it starts with only a couple kicks. After giving it gas, the engine sputters, backfires, and there are popping sounds comming out of the carbs. The engine wont rev over around 3600 RPM and after running for a couple minutes it fouled the spark plugs(they were dry with black soot). After it runs and I pull the spark plugs, I hear sizzling comming from the cylinders and a little bit of smoke comes out of the carbs when I take the air filters off. I tried playing with the little black plastic screw on the right carb while it was running and noticed nothing(is this the air/fuel mix screw?). Is the engine running too rich or lean? Is this just a matter of rebuilding the carbs?
Thanks
