I received the order quickly. I opened the package and observed the primer bulb was slightly smaller than the original I took of my McCulloch SE 2000 chainsaw, however the housing appeared to be the correct size. I installed it on my chainsaw and it fit and works as it should. 👍. I did receive a message from the seller asking if I had any questions or concerns. It appears the seller has good customer service if you have any problems, I would not hesitate to order from this seller again.
