REMOVING YOUR CARB: Detailed instructions
First I will assume you can take the linkage, choke coil, and vacuum lines off.
PLEASE remember what you un-did to redo when you get your carb back. WRITE IT DOWN,
draw diagrams, take pictures, I don't care! I can't be there to help you in person
to put it back on. But, you can call/e-mail me if you need help. No problem.
TOOLS YOU SHOULD USE
A flare wrench and a LARGE open end wrench. Typically a 5/8" flare and a 1" open end.
NOTE! There is usually a vacuum port (nipple) sticking out of the carb which will
deny you access with the 1" wrench around the inlet fitting. No problem! With a
pliers 'gently' grab the nipple and pull while turning back and forth. NO NOT
USE EXCESSIVE grabbing pressure as this will collapse or flatten (egg shape) the
nipple. It should pop right out. Tap it back in before you ship to me. It's
only a force fit. You will have to remove it again when you put the fuel line
back on the fuel inlet.
HOW TO REMOVE THE FUEL LINE
The key here is to crack the fuel line loose without moving the inlet fitting or
as little as possible. I want that for myself to take out if possible. This is
your basic jamb nut situation. HOLD the inlet fitting in place with CLOCKWISE
force/pressure as you loosen the fuel line with COUNTER-CLOCKWISE force. Use
equal pressure as you crank. These can be a bear if it hasn't been off in a
while. It may take some force. If you have both wrenches on properly, all
you might get is a skinned knuckle when it breaks loose.
See graphic. Removing Fuel line
After you get the fuel line off, you can unmount the carb (4 big machine screws
at the corners). The carb will pop off in your hands. (be carefull of gas in the bowl
That's it! Empty the gas out of the bowl (turn upside down and all around).
Package it up see packaging instructions and ship it off to me.
