    Use 2-stroke oil and coat the parts, don't use sealer on new gaskets unless the machine surfaces are damaged.

    Did you use an anaerobic sealer and prep spray before joining the crankcase halves back together? Or what did you end up using to seal the case halves back together?

    "how the engine runs without oil is beyound me" - sounds like we found the reason for the rebuild jus kiddin, the oil is mixed with the fuel - check it out: http://science.howstuffworks.com/two-stroke2.htm

    the motor is just back from the machine shop. was no need in braking the block apart. during reassembly. the gasket set says nothing about sealers. been a practice of mine in all mechanical parts as cars and so on to use permatex. my question is no or yes. and what sealer to use. pretty simple question.?

    One reason for not getting your "simple question" answered is that different components require different types of sealers. If you don't have a service manual, get one. Even my cheapie Seloc manual describes where and what needs gasket sealer and what kind of gasket sealer. The manual will also explain how a 2-cycle engine works and is lubricated.
