Thank you for your question.
I am sorry you are having a problem with the blower. I have looked up the model number you have submitted. If I remember correctly, you have to remove the carburetor and maybe the muffler to separate the halves. I believe there are also screws in the handle mounts that have to be removed. Once the screws are removed, try to take the haves apart. There is a rubber mount on each half that can stick. The mount is towards the center so the edges should spread with a straight blade screwdriver. I wish I could have been better help it has been a few years sense I have seen this blower.
Please feel free to reply below with more details and I will see what I can do to assist you.
