Hi all, In the last week, I finished my first build, however, I've run into some issues in adjusting the carb. The carb runs perpetually lean, and I can't get it to run rich as to better lubricate the engine during the break in period. I've moved the c-clip to the very bottom of the needle, and it only runs with the choke all the way on, otherwise it will shut off. I've done spark plug checks, and it appears "normal", as in a little bit of carbon at the base, and chocolate colored at the tip of the spark plug. At this setting the engine doesn't get super hot, and provides decent power, but burns an incredible amount of gas. However, at any other setting, the spark plug will turn white, and the engine will run extremely hot. Hot to the point that it actually melted the rubber gasket at the base of the CDI cable to the spark plug. Specs are: 80/66cc chinese kit off ebay, stock carb, 26 inch wheels, 44 tooth rear sprocket, 20mph cruising speed.
