Not arsed lol, just don't use them. Some of the flywheels have cast in keys. Grind them off and do as above. The key is really only there to make timing easy anyway. Just a preference I guess.

Thought I'd toss these on here for your amusement. Not me, but this is how I clean cylinders.
This guy is considered a master with 2 strokes in saw world. Has a ton of vids about porting and what not.

What is it ,that is in there that he is taking off ,an why?

Ive done a lot of mechanic work on these small engines ,but only the basic trouble shooting & repair jobs
to get a unit fixed & running for people ,so this high performance stuff is new to me!...:unsure:

So in order for me to understand it ,is for someone to tell me why ,then someone showing me on the
Y-tube to just do it an how!....I would love to learn!....:cool:
 
So when you have aluminum transfer from a piston there are really only a few methods for getting it out. Either acid, like Todd mentioned, or the method I posted (and use) is to sand or "buff" it off the cylinder.
I used to use the acid method and found it to be wanting and too much work. If theres a tiny crack or pin hole in the plating on the cylinder, the acid will get in there and make it worse. With some care you can sand the alloy off and get back to square one. Cant be reusing a cylinder that's had aluminum transfer stuck to it. Thought you may find it informative.

Ah ,yea I wont be using no acid ,my acid trip days are over!....:whistle:

However ,I would like to do some porting as I am handy with a dremel ,but for now ,I am just watching a
ton of vids to see what areas that are being cleaned up ,who dosnt want to squeeze a little bit more power
out of their engine ,even the wood cutter wants a souped up saw!...:giggle:
 
Hear hear! Most of mine are ported. don't have any apart atm that are in need. In rc we have a leg up, as we can easily run tuned pipes, and have room for reed blocks and whatnot. Saws not so much.
I'd advise getting a flex shaft for the dremel, and hanging the dremel up on something to help keep the shaft straight ish. That little pen really helps to get into these tiny ports. A foredom is better but not needed for the hobbyist. Imo.
