    1988 Johnson 110 vro v4 sputtering at idle

    Yes I get what your saying about the fuel pump. I mean I can order it it'll probably be somewhere around 30$ to 40$ for a new pump which doesn't bother me. It's a learning experience but I can't really put time and effort into this motor be I need it for tournaments and knock on wood it's always...

    1988 Johnson 110 vro v4 sputtering at idle

    1988 Johnson 110 vro v4 sputtering at idle

    I've got a 1988 johnson 110 vro v4, the vro is deleted and I mix the fuel. I am the second owner of this boat and just bought it a year ago. I have completely done a redone the boat and motor. The motor has a vacuum operated fuel pump on it. Compression is all good in all cylinders along with...
