Customer Question

I have a Johnson 140 4 stroke. It was great when just starting then after a while it starts to loose all power and then will catch up and keep doing this. It will not shut completely down, just loose rpm and then revs back up. You can back it down below 3000 RPM and it will run fine.

It looks like you read my reply and logged off. The website did charge you to speak with me. Was this something you still needed help with?
