Old school carbon removal

[rookieshooter]

Just wondering if any of you Old School guys ever used this form of carbon removal in the combustion area?
I've done it and it worked so good that the engine ran worse What I'm I talking about. That's right worse. It removed so much carbon that small pieces actually got caught between the spark plug electrode and tip.
So after cleaning several spark plugs and reinstalling, it ran great.
Now this was on a carbureted engine.
It goes like this, get some alcohol and put it in the freezer. It won't ice up so it stays in liquid form. Then when good and cold and engine running. And reaches op. temp. Remove air cleaner, and slowly pour directly into carb bore. The engine will spit, sputter so you will have to manually operate the throttle and keep reving it up. I'm guessing that it works due to the extreme temperature differences. And it would reason that the manifold runners are cleaned also. I noticed also that it came out in pieces, not a gooy mess, but hard stuff.
I'm not taking any responsibilities on this quick fix. But like I've said, I've done it and it works. I even used one of those scopes to check out the piston tops. And sure enough there was a substantial amount removed.
Now don't dump the whole jar at once, or you might just hydraulic the engine.

My dad used to do that when I was growing up. He would also add a bottle of alcohol to the tank when it was under 1/4. He said it worked just as good as those $8 injector cleaners.

Glad to hear that. I might just do the alcohol thing in tank. The more things change the more they stay the same.

I never even heard of Seafoam until I found this sit. After reading so much about the stuff I did a little test and got some carbon up crap like old valves, spark plugs with tips crudded up. And then soaked in Seafoam. Did not impress me at all. I'm not saying it does not work when applied per instructions. But I surly thought that it would do better in more or less a static test.
