Carburetor Cleaning


Carburetor Cleaning Basics with Greg Stewart

Often times we get the old scooter out in the spring and with a little effort – it’ll run just fine. Other times, you are not so lucky as the gasoline left in the machine has turned into a substance very nearly like road tar and has occluded the jets. This will be a brief tutorial on the basics of getting back in the saddle again.

Once removed, you typical carburetor will look something like this. This is a constant velocity Mikuni – a very common and popular design.

Carburetor removed from motorcycle

Start by removing the float bowl to inspect for dirt, debris and other detritus that has formed over the winter.

Float Bowl Removed

Mixture Screw

This is the idle mixture screw – screw it IN and count the turns BEFORE removing it so that you may reset it easily.

O-ring and Spring

Most mixture screws have a small o-ring and a spring on them – be careful not to lose these!

Carburetor Jets

Here are the jets after the float and needle valve assembly have been removed

Main Jet and Holder

Here is the main jet and holder removed from the carburetor


Remove the diaphragm as well from the top of the carburetor to inspect for tears or rips.

Thoroughly clean all the parts, taking care to assure that spray solvent passes through all the jets and jet passages. High pressure shop air is the best for this process – but careful cleaning will often suffice if the motorcycle has not been sitting for too long. Be certain to take special care in cleaning the idle / pilot circuits as these are the smallest and are most likely to collect debris. Assemble the carburetor in the reverse order of disassembly and enjoy the ride!
