Lately, I've seen kits that include a carb, AF, plug, grommets, and fuel lines for small two strokes on eBay and Amazon for as little as $12-$15.
I've used a few, and only had trouble with one spark plug; carbs and other stuff have been fine.
Have I been lucky? It's not worth repairing the original carb at these prices.
I figured you guys that do this all the time would have experience.
