Before disassembling the carburetor for cleaning, a well-illuminated, clean surface is essential to good
carburetor cleaning. The best cleaner for the carburetor is a spray type carburetor cleaner. The pressure in
the can works to dislodge dirt, and the chemicals aren't as caustic as dip tank cleaners.
NOTES: 1. A carburetor is not repairable if it has a damaged body casting.
2. Carburetor cleaner will not clean water corrosion.
1. Begin by removing the float bowl. If the inside is
not gummed or corroded, you can remove the jet
and use carb cleaner and a jet cleaner to clean it.
2. If contaminants are found, it is probably a good
idea to drain and flush the fuel tank.
3. Remove the main jet and clean any dirt and/or
varnish from the jet and float bowl.
4. Use a "cabinet" screwdriver to remove the main
jets to reduce the possibility of damaging the
threads.
Carburetor jets are brass and they need to be
treated with care and respect.
Here's a cross-section of a jet. The orifice has
transitions for fuel to enter and exit with
minimum of turbulence.
Here's the same jet, clogged by a winter's
worth of gasoline plaque. Not much gas will
flow through.
And this is what the jet will look like: So much
for the smooth transitions.

This is what they're supposed to look like.
Each hole is precisely sized and shaped,
and your goal is to clean them out without
reshaping them.
A good technician will select the correct jet
cleaner to fit this jet size and gently clean
out the deposits.
Just remember that the result of your effort
should be a jet that's clean as new, without
any modification to its shape.
And remember, there are passages in the
body that need to be clean, too. Spray
cleaner through all the air and fuel
passages until cleaner flows freely.
