iv just got a 19mm tnt carb got it secone hand and got a manifold and fitted them got it all running,and when to adjust the air/fule mix and the flat head on the air/fule screw half of it snapped of so now i cant adjust or remover it now. can anyone help? cheers
clamp it with plyers or molegrips to get it out /adjust you might need to file two flat spots for grip
And tnt carbs are generally totally shit. So it might be best to plan for buying another one in the future.
