Superjet not running right

Hey, i have a 1990 superjet. It has always ran perfect until a couple days ago. It still has good power, but it stalls after about 50 feet. The engine doesnt even get hot so its nothing heat related. It seems like the carb but I took it off and cleaned it up and everything looks good. The motor is also getting fuel. Do any of you know what the problem could be? Like I said, the motor still makes good power when its running for the short time that it does... Thanks

Check for an exhaust leak, that is real common.Remove the hood and fire it up cold be sure you have good light so you can see all around the pipe coupler's and also the exhaust manifold.

I dont think its an exhaust leak because it still stalls with the cover off and i dont see any smoke under the hood. Thanks for all the reply's so far. As long as there is fuel going to the motor i would think there is air going in the tank

try a loose gas cap (on trailer) and see if that has any effect
also check fuel filter- partly plugged will allow an idle but whne you give ti gas it dies
or an air leak in the fuel line . . .
