According to page 62 in the Stihl user manual: Spark plug (resistor type): Bosch WSR 6 F Electrode gap: 0.02 in. (0.5 mm) http://www.stihlusa.com/WebContent/CMSFileLibrary/instructionmanuals/STIHL-MS-210-230-250-Instruction-Manual.pdf

Chances are good that the compression is not to blame. I would look at:
1. Bad Fuel
2. Fuel Line/filter
3. Carb dirty/mis adjusted
3. Spark Plug
4. Ignition

1. Check Idle settings.
2. Check Spark plug some plug is bad if engine heating!
3. Check all sealings, first check gaskets between cilinder and carburator, then crancase sealings.

sounds like the engine has seized up. SORRY. did you mix the fuel with 2 cycle oil?

ck.the oiler drive gear behind the chain sproket

there's a wire that gors from chassis ground through a switch to the coil. look for a broken wire.

This depends on the language you are best at reading. Many great physisists have come from Germany and Austria. You may want to look into the language that is best understood by you.
Special Therory is difficult enough to usderstand in your good language let alone a foreign one ;)
Good luck

remove chain plate, clean all check oil drain is clean. check oil tank cap, is ther air inlet clean.

check also gaskets between cilinder and carburator.

33RS chain goes dull faster because it is a full chisel chain. Stihl chain is prestretched and will only stretch if heat builds up. Make sure your oiler is putting out more than .3 ounces per min at 13,000 rpm and if any chrome is peeled off of the chain swap it for a good one. Dirt takes less than .003 of a second to dull an entire chain.
check with a local dealer like www.arcolawn.com to see if your machine can be fitted with a carbide chain that can last up to 4 times as long in dirt and hard wood.
Good luck

I would recommend checking the flywheel key. It is not common but if the clutch had been removed with an impact gun it may have sheared the key. You can do this by removing the starter and flywheel.
consult a local dealer like www.arcolawn.com for Stihl parts and tools.

Best wishes,
