Mcculloch Eager Beaver 3.4 No Spark after it warms up.

I just got this saw (orphaned) , I know why now possible ignition issues. I put a new chain on it and started it today and made several good cuts but it progressively got a engine boggs and tnen quite. I pulled out the plug and it was wet with gas. No sign of spark.
Anyone have any ideas as to what to check next ? It has a solid state ignition , which I thought were pretty reliable. I don't want to just start changing out things without a good idea why?

It could be a carburetor problem or possibly an incorrect fuel/oil mixture but my first guess is that it is running too rich. Make sure the air filter is clean and try giving the spark plug a good cleaning and see if it runs. It could also be suffering from too much oil in the gas but if it runs pretty decent for a while I suspect the carb. more.

If it runs and seems to cut in and out or dies like you flipped a switch, especially when the engine is hot, then I suspect the coil is going bad.

You say no sign of spark. Does that mean you've visually checked with the plug grounded for spark?
