The older Stihls are the same (starting-wise) as the new ones. At least all the 0xx series saws that I have used, compared to the newer xx0 saws. Overchoke them and they will all flood. The trick is to be sensitive to the pop, rolling semi-start, or rumble of the saw with the choke set on full. On my 025, the saw will actually start for about 10 revs. Almost time to reset the choke lever and keep it running, but never enough. That saw does not have a gas vent like the newer ones have. On the 361, I get a 1 or 2 rev pop, and that's it. If you miss that, and pull with the choke set again, you will flood it. Once flooded they are a pain to start. May as well set them down for 20 minutes and let them air out.
Flooding while starting with a decomp button depressed is common on Stihl saws. The LA fire department put out an order to tie off the decomp buttons on all their Stihl rescue saws with zip ties so that they cannot be depressed when starting (or at any other time). I like the decomp button. I use it a lot during cutting when restarting the 361. I wish the 290 had one.
If you want a hard saw to start, try the Echo CS-3000. That thing has to be drop started one handed, while you open the throttle all the way, or it will flood. One huge feature that I like about all the Stihl saws is that they all have the same lever action, and they all pretty much start the same way.
