Servicing 2-cycle motors
 

Does anybody know of any good books where I could learn about servicing small 2-cycle motors?

I have a couple of Stihl weed wackers, one of which has lost power since it was new. I would like to be able to adjust the carb, replace the rings, and that sort of thing. Where do I go to learn about that type of thing?

Not much to learn..if you know 4 stroke engines you can deal with these easily.

In most ways they are simpler.

I'm serious...if you can maintain all that farm stuff you have doing one of these is a breese just by using common sense. There really are that easy.

Just keep the work area clean..and remember gaskets are important. You will see what I mean. Make a note of have far in to turn the carb needles before they seat and write it down..thats the hardest part of all of it.

I completely overhauled a motorcycle engine at 12 years old with no manual....and never needed any help from my father.

I'm sure you can handle this easily.

Yes, 2-strokes are very simple and easy to work on.

Im am presuming that you know the basics of internal combustion engines in general but, if you dont it is best to start under the engine section of www.howstuffworks.com

Replace the cylinder, piston and rings and you should be good to go:). Should be able to get the parts without spending alot of money. Oh yea - don't forget the gaskets.

The rings are pinned on the piston to keep them from rotating. When you install the cylinder you must have it lined-up or the end of the ring will catch on a port and make a me$$. Over tightening head nuts can warp the cylinder and cause four hotspots and failure. Crankcase is sealed and must hold pressure.

Manuals are available, ask at a repair shop. Check eBay, probably get 500 manuals on CD for a few bucks.
