I had the same problem as you, I looked for a month for a primer bulb. I found out the nearest McCulloch dealer was in Janesville WI. It's a Blaines Farm and Fleet and they ordered me the part from the company. They will need the model # and serial #which are on the bottom of the blower. The phone# there is 608-752-6377 Hope this helps. I have the McCulloch super air stream IV gas blower/vac
