Made a nice discovery a few days ago!

Decided to try Evinrude's "Engine Tuner" to clean my disassembled OS .70. Worked like a charm, dissolved all carbon deposits and fuel residue. I've also used it on a papertowel to clean aluminum heli components.

Engine Tuner is used to decarbon your Evinrude/Johnson outboard by spraying into the carburetors or throttle bodies if you have a DI or an E-TEC. You spray a liberal amount at idle until the engine stalls and allow to soak up to 16 hrs, then restart and run to remove deposits.

I soaked my OS.61 in place and just used my starter to roll over with glow plug removed. Quite a bit of goop came out.

The lot I got is not a lot, but I thank God a lot for the lot I got!

Actually its more than just diesel or kerosine. Its a very high detergency cleaner. It also dissolves varnish from your gasoline carburetors.
This is available from your Evinrude dealer in an injection can for attachment to your outboards schrader (maintenance valve) or a regular WD40 type squirt tube.
It has a rather pleasant odor as apposed to using diesel or kerosine which won't dissolve the varnish and carbon left from glow fuels.

The lot I got is not a lot, but I thank God a lot for the lot I got!

old castor engines build up varnish which helps seal them. especially non ringed engines i'm meaning here. which most old plane engines are.

the Wasp,
I don't have a "link", however, the part number is (775627).You can pick this up at any BRP Evinrude/Johnson dealer.

I've been an Evinrude mechanic for 27 years and this stuff works! All Evinrude/Johnson 2-strokes are manufactured with strong crosshatch patterns in the cylinders, this is mainly for good oil retention. Also the oils being used have high detergent levels to keep carbon down. When you get engines that haven't had good or proper oils used in them, this causes what is called glazing on the cylinders (carbon deposits filling-in the crosshatch) which cuts down on the lube being retained.
The cylinders on the "ringed" glow engines that I have, also have this crosshatch pattern. So I'm inclined to think this may be a good thing.

raptorheli2,
I don't have any experience with the ABC or non-ringed engines, so perhaps someone else could chime in on this one.

By the way, it also did a great job of cleaning the glow plug element.

The lot I got is not a lot, but I thank God a lot for the lot I got!

its just light nafta. Its the main component on every single carburetor cleaner I know (and also PCB board cleaners). Works very well btw
