well you have to do it one step at a time, check the idle circuit, check the plug and then make the adjustments, one you have that perfect, do the needle, with 1/2 trottle plug checks, the the main, you have to get the bottom end working good, then work you way up, it's the only way to do it, takes a while but it works
