What type of problem are you having with your blower?
The exhaust ports on your cylinder could be clogged, or the spark arrestor screen on your muffler could be clogged. You will need to remove your muffler, in order to clean your exhaust ports. You can clean your spark arrestor screen with a blow torch, after you remove it from your muffler.
Please take a look at the image in the link below.
