Primer bulb is on the left side of the saw, middle at the top.

The primer is a recent addition to the 345's. Something else to replace when it hardens and cracks. :

Yes I suppose it something else to replace, but it should last a long time, I ve had a weedeater for 5 years now with one, and it has no sign's of cracking or getting old yet, and still works fine.

and when it does crack it is a 5.00 part and snaps in under 60 seconds.
It also saves wear on the starter rope and related parts. Will worth it.
Related parts also includes the person starting the saw.

I agree, its such a little thing, nothing to worry about.  Definitely didn't influence my purchasing of the saw.
