Hi, I’ve bought a little GZ125 as a project bike. There are starting and running issues, which I’ve put down to a hole in the diaghram. Looking online I can get a replacement diaghram for £30 or a replacemant carb for the same money. I have two questions, Firstly, does anybody have any experience with these carbs, Secondly, the carbs look like they don’t have a TPS fitting, does this matter, can I lose the TPS? Cheers
