Since last summer, the 1996 Johnson 112VR was a little sluggish out of the hole, and would conk out on me, but would always re-start. From timeto time, the bulb would deflate, but if it stayed hard the motor ran fine.
Anyhow, when I put it up last October, it wouldn’t turn over at all. Yesterday, I got it to run on the ear muffs, as long as I kept the choke pushed in. After 30-45 seconds, even with the choke in, it would eventually die.
I’ve had this boat since 2001 and have never re-built the carbs. The fuel pump, bulb and gas lines, and the fuel separator are all new. Does this sound like a carb problem? Thanks.
I had a sim issue one time on a boat with a in hull gas tank. It was the anti-siphon valve on teh top of the tank. It prevents a fire from traveling the fuel line back into the tank. The ball valve inside the anti-siphon valve would get stuck & just kept getting worse & worse. I took it off & knocked the ball out with a screw driver & hammer & no more problesm so then I replaced it, $5 or so. Might work…
Well, it was the carbs. We rebuilt them today and the Johnson is running like a top. It wasn’t nearly as bad as I thought it might be.
It was my first time removing carbs from an outboard, and I was pretty intimidated with the whole prospect of it, but we got through it with no glitches.
