You are giving up to easily. Chainsaws are really quite simple to work on compared to other engines (like 4 strokes). You were being mis lead buy this group (crispex) into thinking this was a timing issues. Believe it or not, adjusting the carburetor has No (zero) effect on the ignition timing.
Since you seemed to be flooded out, deal with that first. First drain the gas tank. Then compressed air into the carb throat while you slowly pull the starter rope is very effective to dry out the engine of fuel. Then pull and pull and pull til your spark plug is clean and dry. Then squirt a tiny bit of fuel down the carb and see if it pops. This should tell you a lot.
For what it is worth, I had a neighbor drop off a saw he severely flooded. Before I learned to dry out the engine with compressed air, I pulled and pulled on his saw, had to be 50 or more pulls, before it popped. Flooding can be a b*tch, but giving up does nothing to solve the problem.
