I've got a couple of carbs off a 66 1600 that are gummed up and won't let
fuel
flow thru from sitting with gas in them for who knows how long.
Anybody with experience cleaning these up.
I was going to dunk them in carb cleaner, but want to make sure it won't
damage anything inside. I've also heard Pine Sol works well as a carb
cleaner.
Thanks, Larry
The factory recommended gasoline. Not a good idea. Berrymans chem dip is
good stuff. I have two cans. Parts go into the old one first then into the
newer
one. When the old one gets too nasty I pitch it, get a new can and make my
former new can the old one. For a basic rebuild this followed up with some carb
cleaner spray works fine. I like the NAPA house brand carb cleaner. Works
well and less expensive that the name brands. After cleaning some Silicone
spray will help get the linkages moving. Don't use WD-40 or such things as
they
will gum things up in a hurry. To loosen them up on the car carb cleaner and
silicone spray is the answer.
For the full treatment I disassemble the carbs, pressure wash the bits,
glass bead blast the bodies and outside of the domes. The pistons and inside of
the domes are cleaned with Berrymans or carb cleaner spray. Do not clean the
pistons or inside of the domes with anything abrasive. They are about a .002"
fit and it doesn't take much sanding to prevent it from sealing. Then your
piston will not rise.
After all that rambling, remove the domes, pistons and float bowl covers and
dip them in Berrymans. Be very careful with the dome and float cover screws.
They are pre-ISO metric and are impossible to find as they have not been made
for decades. If they don't want to come loose with a screw driver grab them
with a small pair of vice grips.
