    VRO delete fuel mix ratio?

    You see the far right plug is white while the others are tan. That white plug comes from a hole that is 10# under 120psi...maybe less than 10# (lbs) only

    I must apologize...my bad. I was trying to go by memory. It's not the ground wire...it's one of the 2 black/yellow wires coming from the ignition.one of the 2 black/yellow stripe wires has been capped off

    1986 90hp johnson primer bulb collapsing..hear me out

    Well, I'm reporting back with an update. I've purchased a Sierra non vro fuel pump and deleted my vro. The switch over wasn't too bad of a job.two hr.job. I also installed a new primer bulb and lines from tank. Zero smoke, starts right up with the touch of the key(it's never done that). My...

    1986 90hp johnson primer bulb collapsing..hear me out

    Well, after a couple more hrs of tinkering, I've come to the conclusion that it just may be the vro pump. Does anyone have an idea how long one of theses vro pumps will last before needed replacement or rebuild? It's a 1986 engine. I know the previous owner so I'm going to ask him if the vro has...

    1986 90hp johnson primer bulb collapsing..hear me out

    Perhaps I should hook the vro back up. The reason I disconnected vro is first start up this spring I had terrible smoking...worse than ever...so...maybe fuel pump not working?.i always have too much smoke and poor starting issues with vro. I took the fuel/oil pump apart not long ago, she looks...

Yes ,I have tested the tank and the fuel does flow on its own " down to the floor" I no longer have a collapsed primer bulb, I do still have to pump the bulb to keep the engine running now though.the collapsed bulb happened only at the start of these issues. Would...
