Brian,
Here are a few things to check:
Fuel filter. Don't rely on blowing through it, pour fuel through it, it
should run right through.
If there is a problem with the shaft you should feel resistance to
turning the cutting head by hand. There is a centrifugal clutch between
it an the engine.
Try another (new container of fuel/oil, just in case something is wrong
with what you have.
Peace,
Pat
