About 2-3 years ago I rebuilt carburetor, put new fuel pump on it, put new water pump in it, and replace plugs at beginning of each spring. It was running great and one time near end of last summer we were cruising across the water when it suddenly dropped rpm’s. It has been running lower rpm’s...
Ok thanks. I checked and is running on both. I saw on YouTube the butterfly valve in the carburetor might not be opening all the way. Is that a possibility?
The rpms on my 15 hp 1976 Evinrude outboard suddenly slowed down and I can not get it to run the rpms it was before. Any ideas on what needs to be worked on? I rebuilt the carburetor about 2 years ago.
