Hello! I have been working on restoring a Tecumseh HS40 engine for a mini bike and I would like some help identifying a problem I am having with it.
I have recently bought a new knockoff carburetor off of eBay for the engine and installed it on the motor. This motor hasn't ran in a long time so when I started it with the choke open it wanted to run rough and smoke a lot.
Eventually the smoke cleared up so I figured I would take it off choke and see how it runs. When I close the choke valve it always wants to die and it will not stay running. I've tried adjusting the idle screw (the screw at the top of the carb by the throttle) but have had no luck. Are there any other adjustments that I need to make on the carb or does my engine possibly have a different problem that does not involve the carb? I'm new to HS40 carbs and do not know entirely how they work.
I appreciate any help I can receive.
