After fighting with the carbon and oil crud using a combination of rags, scoth brite pads, degreaser, sea foam, and carb cleaner, I was thinking that there had to be a better way...Then I remebered a tip that I got from one of the Pol. sites a few years back. Easy Off oven cleaner. I sprayed it on, 80% of the crap melted away, sprayed again and worked the valve over with the scoth brite, cleaned with a rag, followed by sea foam and a plastic disposable scrapper.
Worked good for me! Seems like the easy off is a real time saver.

dont leave that stuff soak on there (ask b2so), it will eat the coating and the metal if left too long. my tip is spray off with carb clean and rag, get loose stuff off. then use a new razor blade and scrape the baked on stuff off. you must be careful so you dont cut yourself obviously, and that you dont narf up the coating too much on the valve. after you have most of the stuff off, spray on carb clean, use a red scotch brite pad and remove the remainder of the gunk. clean well with a rag, coat with two stroke oil and place back in the cylinder. takes less than an hour for all three. ski
 
I was the one who was the one to recommend the aircraft paint stripper. It doesn't go through the coating at all and gets the build up pretty loose. Just go at it with a wire brush and that stuff and it turns into a job of minutes.
 
I just did mine and I found dipping in carb cleaner and using my Dremel with a small buffing wheel worked awesome, never harmed the coating and shined up like new, be sure to wear rubber gloves and safety glasses, HAPPY CLEANING...PRAY FOR SNOW!!
 
The easy off was only on for a minute or two, followed by a wipe with the rags followed by a final cleaning with seafoam, and wiped
I figured that anything that worked right away was pretty strong and should not be left on.

The best stuff I found and the easiest way, Mercury PowerTune, Start motor, spray in airbox, motor stalls, let sit, start motor and give a little gas. Your motor is like new and cleans everything.
 
Why would you clean your motor? You want to leave the carbon on top of the piston and on the heads as it is free compression. When you wipe that out you are loosing some compression. Also, this stuff will not be able to clean the power valves. Only way to clean them is take them out. I would not do that in the future.
 
I use brake clean and a chunk of brass or a brass puddy knife, you guys think this would harm the coating? It works, but a little labor intensive.

I second that - i use the orange citrus based solvent like goo gone or even the golf club grib solvent and then use a scotchbrite attachment on the dremel and it's done in minutes.

Hey Wooly,

Were did you buy a scotchbrite attachment for your Dremel?

if you go to walmart or a big hardware store, the dremel display will have some of the scotchbrite wheels for the dremel - i think they come in two different levels of courseness. They don't last long, I probably go through 2 of them cleaning my valves, but they work good.
 
seems like alot like to make a big project of simple things. Mine always whipe off brake cleaner and the big depsosits scrape off with razor blade whole job takes me no more then 15 min max.
