Some weeks back there was a post that mentioned GM Top Engine Carbon Cleaner as doing a great job on barrels.
I checked with a local Chevy dealer who provided a part # (10050002), but said they were out of it, and that it isn't available anymore. I seems that it was used on carbs, and the new cleaner is sold in a kit form to service fuel injection for 2 or 3 hundred dollars.
I tried another dealer hoping to find leftover stock. He had "Upper Engine and Fuel Injector Cleaner" in a spray can with a different part # (1052626) for $10.
I guess it's the same stuff. Haven't tried it as yet.
GM TEC as many know it by is an execeleant carbon cutter for barrels. Yes GM discontinued it several years ago, but it was replaced by GM Upper engine and fuel injector cleaner (Part Number 88861802 this is a 16 oz Bottle) I have never tried the new stuff as the price has trippeled (GM TEC could be bought for around $5 bucks a can the new stuff I priced at $27 bucks.) It also is a diferent color than the old TEC as TEC was a yellowish color the UE&FIC is blue in color. I have heard mixed reviews as some say it works as good as the old stuff, and some say that it doesnt. I tried sea foam, and it is not the same stuff, and it did not work. I been told that "Mercury Power Tune" is the same thing as GM TEC but in a spray can, and it is availble at marine dealers. (around $5 bucks.)
Go to any Chevron Station and get "Techralyne" (sp..??), it gets the carbon out!
the injector cleaner ???
heck costco carries a 4 pack....

P/N 1052626 in a spray can is a decent cleaner and should be fairly cheap. Its nowhere near as good as the old stuff and its very foamy. It may be the same stuff as P/N 88861802 plastic bottles as both are called Upper engine cleaner but I havnt checked to be sure.
If Mercury power tune is the same as the old TEC I'd buy a case
I tried some of the new GM cleaner and it didn't work as I expected. I use the Bore Tech carbon cleaner and it works way better.
The best carbon cleaner that I have found is a product called SLIP 2000. It is a carbon cutter designed for shotgun chokes and such. A wet patch to get the bbl wetted and then a bronze brush. Let the stuff set and do it's job. Your borescope will show you how well it works.
I think Sinclair's sells the stuff.
I bought a bottle of the KG1 Carbon Remover early this year and I find it works well at removing carbon. This is one of several bore cleaning products KG Industries sells for bore cleaning. I have another called Bore Polish that also works well. As well as the KG1 work, I would like something even faster to desolve the carbon. There must be something out there that is more agressive.
there is..but your government has decided its unhealthy for you.......
do some search for the other profducts and buy a bunch...
Here's another vote for KG1 Carbon Remover. It seems to do a good job of attacking carbon fouling.
I use SLIP2000 as the first step in cleaning. It only needs to soak for a few minutes. Then I alternate between it and BoreTech Cu remover.
I find SLIP2000 actually works better than GM-TEC and definitely smells better.
I'll stop at COSTCO, pick up some injector cleaner and see how it works. I'll be surprised if it works better than SLIP2000. My supply of GM-TEC is down to about an ounce. I no longer use it for bore cleaning.
I'll also try the BoreTech Carbon Remover. If it works as well on carbon as the Cu remover works, I'll be a happy camper.
I have a bottle of Pro Shot Copper Solvent IV, and seem to remember that it did a very good job on powder fouling. I am not sure that the reports that we are getting are really about hard carbon, or just powder fouling. IMO there is a big difference, and the best approach that I have found is to not let things go for so long that there is a problem. Keeping ahead of the problem is probably the best of all approaches.
its why i say start every cleaning with carbon removver..never let it build up....
been there done that..paid the bill....

Spread it on a patch as if you were spreading a thin layer of peanut butter on a piece of bread.
I'm a GM tech. The old formula is a great carbon solvent, it came in a metal can. You can soak a piston overnight that has 150,000k miles of carbon on it and it will be spotless clean. The new stuff in the plastic jug is about useless.
