Re: Complete fuel and engine cleaning kit
Sea Foam is probably the tune up in a can of choice here, it wokrs really well.
Decarbbing is a different deal, you can't just put it int he tank and have it work btu it is pretty easy.
At some point your carbs will probabl;y become slogged and you will have to actually dissasemble them to clean them but the Sea Foam works pretty good at keeping them clean.
