Good handling, not bad acceleration, roomy enough for me and I'm a big

have to change them every 1000 to 1500 miles.

Weird, never saw anything like that. You sure you
were using the right ones ? Cant see how any
engine can develop a fault that eats spark plugs.


The AMC 232 6 cylinder used to foul #5 pretty regularly. I had one and
2 of my friends had them. We all had the same plug failing. It was
always #5. I figured out early on, you just chipped out the fouling
and stuck it in one of those powder abrasive, air power, plug cleaners
and it was good as new. I used to keep a couple in my glove
compartment along with a plug socket and a crank style speed wrench
under the seat. I could swap that plug at a long light.
You were lucky it was only #5.

The years when they first started using chrome rings many of them just
would NOT break in. A quart in 500 miles at 3000 miles was not out of
the ordinary.
Someone came up with a REALLY simple fix.
2000 RPM, aircleaner off, and sift a few tablespoons of Bon Ami
cleanser down the carb throat.

Went from a quart in 500 to a quart in 1500 almost immediately - if
you did it early enough. If you waited for the rings to carbon up it
didn't work.

Usually did it just before an oil change. I worked at an AMC
dealership in '72

This wasn't oil fouling it was lead (or whatever that white crusty
stuff is). This was always just #5. I could put that plug in #4 and it
would work for years. A brand new one in 5 would foul in a month or
two. This was a throw away 71 Gremlin I got for free but I couldn't
kill it. I just needed to keep cleaning #5.
My buddy had an Ambassador with exactly the same problem. I used to
clean plugs for him too.
