Go to your local NAPA store and pick up a can of Sea Foam and dump the whole
can in the tank. It might take a couple of tanks to clean out the really
dirty systems. It'll keep your fuel system happy, and once you've cleaned
the system out, a few ounces every other tank will keep it clean.

Can anyone recommend a good carb cleaner fuel additive that works? I try
to run out all my fuel after use (with stabil in it) but I would like to
know if there is an additive that can remove the gum from the idle circuit
and float needle that eventually builds up. I have a 1972 50hp Johnson and
I have rebuilt the 2 carbs but it is starting to get a little gunked up
again. It's been 4 years since the rebuild. It is a freshwater Northern
boat that sits for the winter. One of the 2 float needles seems to stick
and free up now and then. Unfortunately it only gets used about 25 hours
per year.

Thanks in advance,

Steve

Better have some good filters inline to catch all the junk that breaks off. The
carb
jets on a 4-stroke outboard are quite fine and it doesn't take much to block
them up.
