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
