What color smoke are you getting?
if it is white then you have a hose cracked or something loose letting air into the fuel line.
Have you checked the fuel filter?
Try running with out the fuel cap, Take fuel cap off and cover with a rag to keep dirt out. the cap has a vent to let air into the tank and can become clogged.
You might try taking off the line at the filter to the tank, fuel cap off, blow about 5 lbs of air into the line, does it bubble ? then how much fuel comes out of the line in 30 seconds? 1 quart? 1/2 gallon?
