hard to start

[john]

I was using my blower and it was working fine then all of a sudden it turned off. From this point on I am having a hard time getting it to run and when I do it will not run long.

Your blower is probably hard to start because of compression loss. If it starts and runs then Dies after a bit this means the rings piston and or cylinder are scored or scratched because of not enough oil in the gas or poor air filtration. If none of those components are scratched up your rings or piston might need replacing. What happens is when it does start when it warms up the cylinder expands from heat and the ring don't expand with it causing loss of compression and thus shutting down the engine.
