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,

If they are gunked up, I'd rebuild them again, then use preventative
measures to keep them that way, using Stabil and starting once in
awhile as Clams has said.
