Try plugging the exhaust stinger with your finger while turning the engine over.
You should see fuel pass through the fuel tubing into the carb, continue priming the engine a few seconds more. If this doesn't work you may have some old fuel gummed up creating a blockage in the carb.
Definitely put new fuel lines on it.
And ditch the old button filter for the new high flow 3.3 filter, or better yet get a new MotorSaver filter. http://www.motorsaver.com/tmaxx.htm
