Hello guys, I have a question for you. I bought a chinese engine (100cc but from what I heard is over rated so is maybe 80?) with a carb like nt one. With that carb idle screw was working as intended (11 turns in). I changed the carb with a hp one, but now the idle screw is all in and I have to tune the throttle screw to have a nice idle. With just the idle screw all in, the engine is not staying at idle speed, is dying. I'm new at this, is my first build. This means that the pilot jet is too small and is not having enough gas? Should I use the jet from the old carb (hope to have same thread size) ?
Edit: 20C outside, engine is starting without choke. If choke applied while running, engine dies.
Edit2: here is a picture with old and new carb. It seems to me that both have same clearence. So the idle screw on the hp carb is not raising enough?
