I have a snow blower with a tecumseh 6 Hp. engine had a carb. kit installed by a small engine...

machanic. I installed it and it still will not start and run. If I remove the plug and squart gas into cylinder it will run until gas is burnt out. I pulled carb. back off and removed the bowl to see if needle was moving or loose and letting gas in. Its loose youu can blow air through it but when I bolt it back on the engine and try it still will not start> What do yuo think might be the problem.
