Rebuilding carburettors is not easy, but certainly easier when as many old internal parts are substituted with new.
The body of the carburettor should be professionally vapor blasted, the internals that are not renewed should be sonically cleaned and that operation should be complimented with, amongst others, new main jets, slow running jets and needle jets. Or, you could by new NOS carbs while they are (just!) still available ?
Check our online schematic to be sure you are ordering all the parts required.

Add as many new parts to the same shopping cart as you wish, new packing sets 16010333305 needle jet sets 16012333004 & float valve sets 16011329004 for example, and still only pay the same single fixed price shipping cost. Please be aware that this component may have other applications within the Honda model range, so check the part-numbers you order are correct for your model and application. If the item you need is not available, add it to your wish list and we will let you know once the item is back on our shelves?
