Re: CJ8 carbon deposits?
I use water myself, but I tried ATF once here while back. Both seem
to work but the smoke cloud put out by the ATF would make a mosquito
fogger proud! Best evidence I've got of it working was this summer
when I changed the plugs - pulled a couple and they had a bit of
carbon on the body close to the threads. Put them back in, fired it
up and ran about a quart of water thru it - I cheat and use a spray
bottle to squirt it in so that I get a steady stream of droplets
instead of a big splash - and when I pulled the plugs everything on
the end looked like new.

When I say 'one massive' cloud of smoke, I am not exaggerating. LOL!

Re: CJ8 carbon deposits?
If you have a hand throttle, that will help. Or you can shove something
into the linkage to keep your throttle open a little. The water will bog
your engine down a little and a little extra throttle helps keep it running.

Re: CJ8 carbon deposits?
If you have a hand throttle, that will help. Or you can shove something
into the linkage to keep your throttle open a little. The water will bog
your engine down a little and a little extra throttle helps keep it running.
