Re: help me start my engine plz

That sounds like a vacuum leak.

Your engine creates a pretty strong vacuum when the throttle is closed, and your carburetor relies on that strong vacuum to feed the fuel when the throttle is closed. An air leak will reduce that vacuum. If your strong vacuum becomes a weak vacuum because of an air leak, then the carburetor doesn't feed the fuel properly. No fuel equals no run.

What kind of carburetor is it?
