If he is going to tear the carb down he might as well have a carb kit with gaskets and change them to avoid doing it twice. Just my two cents.
My thought as well. As you can see in the previous post, I did pick up a carb kit.

I also just watched a video on replacing the impulse line..that looks a little tricky to get on and requires more tearing down. Someone suggested I replace that and I will probably attempt it..looks like a gasket to replace on there as well.
 
The impulse line is quite easy to replace. Get yourself a pair of hemostats,almost a must have these days for saw work, they are very thin and can make access into many cramped openings where ordinary needlenose pliers cannot get to. Fish the impulse line in through the airbox bulkhead where the carb nipple pushes into the hose/line, then attach it to the barb on the cylinder base, there is enough room to do this without dismantling the saw but I most often do take the saw down to clean out all the crud built up in under the crankcase and spline cavities.

Picked up an impulse line, muffler gasket and scrench today. He was out of stock last time I was in, so he stocked up for me. Gotta order a vacumn/pressure tool from Amazon. Plan on tearing it down over Xmas days off.
 
You will get a few responses telling you the center electrode will drop out of that Bosch plug and get impaled into the cylinder head or piston crown.

I've never heard of a spark plug doing that..is this a real issue? I would think the Stihl dealer would not sell them if that was the case? What is the recommended plug replacement?
