the new carbs are alot more like a novarossi carb the idle screw is now situated on top of the carb instead of below and I have no problems with tuning or the engine holding a tune what so ever. they've also gotten rid of the plastic sleeve it's now ali with 2 rubber O-rings

so as to your last statment I think you'll find that GoTech have sorted out thier carb issues if you can get hold of a 2nd gen carb you wont be dissapointed
