Re: Westerbeke 30B Deceleration Stumble/Stalling
You just need to idle the engine up a bit. Its set to close to fuel shut off.
The fuel pump shop should of put that pump on a pump stand and ran it. If that was done then it should not shut down like that.
When the pump is down throttled it should return to low idle and stay there. It sounds as if it drops below fuel cut. Rather than taking it back to the fuel shop it can be reset there on the boat. put a pic of fuel inj pump up and i will point out what to do for you.
