Hi, well its good you have resolved the problem. I wouldnt be so tough on yourself, not many people realise that Honda put the filter inside the tank. Alot of...
I scored a parts bucket and inside are a few spares somebody here might want: ca110/c110 carb body (just the body, barrel, and cap - no screws,jets,bottom,or...
