What the plug for in the crank case on a 2 stroke?

I bought a 14" saw on ebay and it has a 2 stroke engine and runs fine. There is a plug on the bottom of the saw and if you unscrew it and look inside you can see the crankshaft.

I was wondering what the plug is for, is it to oil something important?

I doubt it..... as you know 2 strokes receive all the lubrication they need from the fuel mix. If you're really concerned maybe post a pic. What model/year is it? Later!

My guess is it is a drain for when fuel or other liquids accumulate in the crankcase, you can drain them out and prevent hydro-lock. Sounds like a good idea to me. Have a good one. Geo

Another possibility is it is an access hole to the connecting rod cap nuts. It may have something to do with the assembly of the engine.

Never worked on one of those.
