14.5 HP Briggs and Stratton with a Walbro Carb on a Craftsman LT1000
Model: 287707 Type: 0224-01

She will start with the throttle all the way down but as soon as i take it up she will die.
I've already: Replaced spark plug and gapped it to 30, Replaced intake filter, replaced fuel line and fuel filter, cleaned carb 3 times and replaced bowl seal, checked for good valve movement.

My guess is that i might have a blown head gasket.

Did i miss anything else this might be?

It sounds like compression related component like gasket or valve problem.

I go with the above post, sounds like head gasket you can see signs what looks like oil burning around the valve cover (exhaust).
