Oven cleaner!
I keep telling you guys, you won't have that carbon if you use a good synthetic oil, or at least you won't have as much.
THANKS for all the great replies. In my case I'm removing carbon from a 1974 Mighty Mite muffler on a saw I'm restoring that's nearly done so it's too late to prevent it. I put it in a plastic bag after soaking it with over cleaner and will check it this afternoon.
I think most of the carbon comes in this case from the burned bar oil. EVERY Remington I've worked on seems to have at least some weeping of the bar oil into the fuel through the oil tank pressurisation circuit.

I keep telling you guys, you won't have that carbon if you use a good synthetic oil, or at least you won't have as much. An oil such as Klotz Techniplate doesn't burn, it just goes through the engine and leaves a vapor out the exhaust if mixed right. If too rich, it just runs out as a liquid. I used it in my Suzuki RM250 for years and no carbon. Sometimes I had to wipe the oil off the pipe when I ran it too rich.
Klotz R50 does leave carbon. Matter of fact, it leaves more than I like. That's the only reason I've switched oils.
Paint stripper works well on removing carbon
Another forum member was using Klotz in his Shindaiwa trimmer, it seized the engine from buildup on the piston & rings. His chainsaws run fine on the same mix.
RE: Klotz oil and carbon deposits:
Klotz main market is the ultra-performance racing two-strokes. These guys tear their engines down and re-ring really often. Carbon build-up isn't a problem if your engine is rebuilt every 12 hrs.
I saw the thread on excess carbon on BLSnelling's saw, but he was also careful to admit that he likes to mix at 32:1, and that the folks at Klotz advised less oil. I think we're learning that there CAN be too much of a good thing: there might be disadvantages to overkill.
maybe disrespecting prepackaged mix from the OPE guys is a mistake...might it be that the relatively pedestrian blends on the dealer shelves are really well-suited to the application?
But the real question would be for sopmeone else to try this stuff:

and report back if it actually works.
