<p>I had a 79 Chevrolet wagon w/350 that i had overhauled. It would
foul the #8 plug every 500 miles or so. I had to drive it to San
Francisco. Stopped through Vegas to stay the night. Right at
rush hour, the plug fouled. It sputtered through traffic to the
motel for at leas t an hour. I was ready to junk the blasted
thing. Found a Autozone, bought a set of plugs and changed #8 in
the parking lot outside the hotel. Took off to San Francisco.
Drove around San Francisco for 3 days. Started to leave the hotel
and head home. Just as I backed out of the space, #8 started
missing. I changed it in the parking garage in the shade....
Drove all the way to Gunnison CO before it fouled again. I hit
over 100 for a long time on US 50, loneliest road in America. We
drove from SF to Colorado Springs in a day. When I got home I
rebuilt the carburetor a week later. It never fouled a plug
again... The plug was oil fouling and the carburetor float was
too high. It must have been washing the oil off the cylinder
walls. After that I put another 40K miles on it and it got over
15mpg. It only aver aged 12 going to SF, so t he carburetor was
definitely flooding....<br>

<p class="MsoNormal">My old ’46 Allis WC likes to foul #4. Of
course it doesn’t get much work so running it good and hard at
operating temperature doesn’t happen all that frequently.
Since it only acts up once in a while I keep an old pill
bottle with Simple Green in it. I just leave the fouled plug
in there to soak until the one in it decides to foul. Blow it
out with the compressor and put it in. It’s saved me from
digging around and trying to find another plug in that “I’ll
put it in this bin so I know where it is dilemma” (since I
then forget where that magical bin is).<o:p></o:p></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Going by your
annual useage, you get 3/4 of the year before you foul the
plug. I would just change it and be done with it, they are
less than $3 at NAPA. FWIW, if you could run the splitter
with something else it may help--engines that are in poor
shape run better under heavier load, not piddling.<br>
