I'm having a problem with mine as well.  It idles fine but if I stomp on it and a dead stop, it just bogs and the engine really doesn't do anything until I let off the gas a bit then it takes off.  I'm thinking it's the jets but I'm not sure, I've never had to tune a carb before :(.

Check the accelerator pump and stroke. It's adjustable on yours. Try playing with the settings and make sure you have no kinked fuel lines first.

New accelerator pump.  I think I have a kink in the metal fuel line, though it doesn't look that bad.  I'll have to get that checked out.

How can I tell if it's the fuel pump or the accelerator pump? It turns over and runs fine when it finally runs, but after it sets over night, I have to pour gas in the carb for it to run! I tried patting my accelerator before starting it, but that doesn't help!

That sounds like mine when the fuel pump was bad.  The diaphram started leaking and it would let the gas run back into the tank and suck the float bowl dry.

Had a kink in the gas line.  I installed a new fuel pump, rubber lines and a fuel filter.  Seems to run 10 times better.  Thanks for the tip.

A little update.  After I fixed my little problem, I managed to spin one of my tires with 500 pounds of tube sand and snow tires on the back from a dead stop without brake torquing.  It made me happy lol.  ;D
