Either get the carb cleaned or replace it. The one I'm fighting with has a non adjustable carb, originally. I'm going to but on a new, older style with adjustable needles, in an attempt to solve the lean condition.
i just put aftermarket adjustable on a Tec 5 hp snow motor . Won't idle. Idle needle doesn't change things. Currently running ok on high idle, no load. Waiting for snow. I'm thinking this engine is too worn to handle load.
