just replaced the plastic idle carb screw with a DAB aftermarket one and i cant get the bike to idle. Ive had it screwed all the way in but makes no difference anyone had the same problem and have a solution?? not tried messing with the air screw yet as its a bugger to get to

Does the replacement have sufficient thread length? The oem blue thread compound often gums up the internal threads in the carb body, might want to chase hole with the correct tap...carefully to not allow debris into carb/engine.

Thanks for the input
