First of all, make sure you have followd the correct start up procedure.
(1)Throttle on and locked in start position, (2)choke on and pull a few times. Saw should fire briefly and cut out. (3)Now switch to idle (half choke if applicable) and pull another couple of times. Saw should now fire and run. If you have pulled it too many times in the full choke position you will have flooded the engine. To rectify this you will need two people. One of you should hold the machine steady on the ground with no choke on and throttle fully open. The other should also steady the machine and pull the starter in quick succesion. This could take ten or so pulls but it should start the engine in the case of flooding. Sometimes it will splutter a couple of times before fully starting and it will normally bog down a bit for the first few seconds as it spits out the excess fuel/oil mix.
If you got to point (3) as it shown above, and then the saw wouldn't start, or hadn't fired and died then there could be a few different problems. basic checks are for, clean filter, fresh/clean fuel, clean spark plug (ie, not oily/choked with carbon build up). When checking the spark plug, if it has fuel/oil mix on it then ther is probably aeither a compression problem/air leak or no spark. To check for a spark leave the plug unscrewed but fitted into cap, rest it against a metal part of the saw and pull the starter with the elec switch on. You should see a healthy blue spark. WARNING, do not rest the spark plug near the plug hole as if it does spark it could ignite any fuel/oil mix that is pumped out of the cylinder. I've had many a singed eyebrow from this happening. If there is no spark, check to make sure the cap is attatched securely to the lead,and try repacing the plug. If this doesn't help you will need to get the coil, ht lead and wiring tested.
