The problem will be a combination of things.
1. Replace fuel filter in tank.
2. Replace fuel line from tank to carby.
3. Replace carby diaphragms.
Also before doing the replacement of parts I would be removing the muffler to check the cylinder and piston for damage.
I will look to see if I have an owners manual and upload it next week to the parts list and manuals area under Questions on blowers.
