Crusing at 10 mph

Actually, I was looking for something in the 30-34 tooth range, nothing fancy, just a plain old sprocket.

Joe the small sprockets are for speed. I have a Kings engine and I am not fond of the manufacturer he is using. The porting was the worst of any engine I have, and it was hard to get running well. I ported it and now it is fine. I have a trick for the carb if you think you are willing to drill a small hole in the thing. Let me know and I will tell you what to do. Those carbs are horrible, no idle circuit. Have fun Dave

Dave, I am after a little more speed/lower rpm at cruise.

Yes, let me in on the secret....is it a way to put a mixture screw in these carbs?

OK it is easy. Turn the carb over with the float off, and near the end that goes to to the engine, drill a 0.040 hole from the float side into the intake runner. I have found that you don't need to do anything else. It then has a way to get some mix air for the idle. I also file a little dent in the slide over the hole, I don't know if this helps but it looks good. Let me know what you think. Have fun, Dave
PS: If it turns out like mine you are going to love the way it runs. Mine will run as slow a good Yamaha, no more balking. Good luck.
PS: One more thing I am running a 39 tooth sprocket and I think it gives the best of both worlds, lower RPM and still pulls well. With the porting and the carb it will still pull off a stop without pedals.

Makes sense, I am definitely going to try that.
