Decarbing piston

[Hamsta44]

I Have a mint Husky 50 which has done very little since I bought it new in 1988. Still on origional chain which is approx half way in the wear stakes.
But I would hate to score the bore so how often should I de-coke it? I have always run it on 32:1 mix (synthetics).View attachment 260546

Amsoil at 50:1, I have loads of hours on many saws and no carbon build up.

Run a good high quality full sythethic mixed 50:1 and you shouldnt have to worry about carbon.......

I do this to my older sleds...

Get to the carb throat, and have it running. Mix a oiled batch of Sea foam engine treatment, and bog the engine out on that. Kill it, let it sit for 15 Mins! Then upon startup, itll effectivly burn the carbon (or most) off.

Works SWELL for me, and NO engine issues to date!

You have half of first chain left on a 24 yr old saw? You sharpen it once a year?

I don't think carbon buildup should be an issue with that low hours i you're using decent oil and your saw isn't way rich.
