Just though this may help some of my non gearhead buddies. Copied this from Tinboats.com:)
Starting a 2 stroke is all about how you go about it. You want to avoid flooding it at all cost. My procedure when cold, is open the breather on the tank, squeeze the bulb till it's firm no more ,then full choke with the throttle open about one quarter until you get the slightest pop,(it's very important to not pull it anymore on full choke after it pops as this is when most flood there engines) then half choke till it fires, let it run on half choke for 30 seconds or so and then open the choke and clear the motor letting it warm up for a minutes or two. If it fails to fire on half choke open the choke and pull a few more times before you go back to full choke. When warm usually just pull it with the throttle cracked slightly and it will fire. The one thing not to do is keep choking it when it fails to fire. Pull it over a least a half a dozen more times with the throttle 3/4 to full open and choke open because it probably already has to much fuel in it and if you must choke it only for one or two pulls. Once you get the plugs wet they won't fire until they dry out. One way to dry them is hold the throttle full open with the choke open and pull till it fires, it will help to unhook the fuel line while your doing this to avoid anymore fuel going into the motor, you can also pull the plugs to dry them, spinning the motor a few times with the plugs out to clear any unburned fuel, (be careful when doing this, keep the plugs and wires away from a ground that will cause a spark and possibly a fire, it's happened to me!) if you put the plugs back in a wet cylinder they'll just get wet again.
This procedure has worked for me on chain saws, trimmers or anything with a 2 stroke motor. I seldom have any trouble starting any 2 stroke. If you have to choke a motor for an extended period of time, more than 3 or 4 pulls something is wrong with the fuel delivery system.

Realised this info probably don't belong here after I posted it, so I copied over to the boat section. It was late.:eek:

Thanks for posting this here Phil or else I wouldn't of caught it in the boat section. I just recently became an owner of a 2 stroke and learned some of this the hard way....;):D

I'd say its a good place to post it, i rarely check other sections. Your steps are exactly how my Troybilt weedwacker has to be started. They walk you through it in a sticker near the choke.

Sounds complicated. I make sure it's in neutral, squeeze the ball, open the choke and pull and she fires right up. Close the choke and I'm on my way. If it's warm I skip the open the choke and ball squeeze parts.

Sorry about the detail, but I did that for the benifit of those that don't fully understand how engines work. (not gearheads):):):)
