Thank you for choosing Just Answer for the solution to your problem.
My name is Hank, and I am going to assist you with this.


To get rid of a vapor lock, you simply need to let the genset sit and cool down.

If your set has a prime button, press it for 30-40 seconds.

Have already tried this prior to contacting you. Due to length of time before I heard your response, I have taken it to a local repair facility.
