    Re: need help with 20r carb

    The carb on my 20r is being a pain in the ass also. For some reason mine will idle fine but then once you give it some gas it will want to idle at the rpm it was revved to. It takes around 15 sec for it to idle down again. It has no vacum hose leaks. I've tried adjusting the idle and mixture and can't get any results.
