You prolly have a bad airleak,seal the backplate and under the carb with silicone,turn in the highspeed needle and count the turns if your like at 3turns try 2.5 Than lean the highspeed. your drowning the motor with fuel. If you drown it again take the plug out & turn your kit upside down and crank the motor to expel the axcess fuel..I'd take the glow plug and put it on the igniter to see if its glowing.If its still good it should glow brite orange,make sure to burn off the extra gas and before you put the plug back in. if your spiting fuel its way to rich try setting the lowspeed flush with the slide arm on the carb
