air leak somewhere?? did you replace the gaskets on the manifold on the motor then where it connects to the carb. it wont be jetting if it was running fine before this.

By "tightening" the 2 screws on the carb, I figure you mean the air/fuel screw and the idle screw. If so, you probably just trashed the carb. Those 2 screws aren't meant to be tightened, just LIGHTLY SEATED. An expensive lesson to learn. Those 2 screws are meant to be adjusted to get your engine to run right. At the bottom of the carb where at least one of those screws sits, is a tapered seat, or tapered bottom to the carb and the screw is tapered on the bottom as well. When you tighten the screw down, you ruin the bottom of the tapered seat and the bottom of the tapered screw. You messed up plain and simple. Deal with it. Expect to have to buy a different carb and don't tighten the idle or air/fuel screw down on the different carb this time. Get a shop manual and read,
