I had a bad spell with my 60horse Johnson VRO (disconnected)today. Havn't run it for about two weeks, took it out today and it didn't want to idle. Took three or four times to keep it going while warming up, then it ran fine so I left the dock for about five minutes,idle/wot all good, then it just dropped back to idle again. Fuel bulb felt empty, pumped it and she opened up, only to die completly within a minute!
Didn't want to start at all then. Bummed out, I paddled back in and brought her home. Took the air cleaner case off, found that fuel came out of air intakes when I turned it over! Drained the fuel bowls, stripped and cleaned the pump type assembly and it seems to run OK now. Does anyone have an idea of what the problem was/could be? Has anyone had a similar thing happen to them?
Exhaust seemed a little too smokey so also wondered if the mix was oil heavy and plugs were fouling. If I get the chance will see how she runs tomorrow.
Was going out with a 'friend' who had just bought a Bayliner..... Maybe THAT is it! My old girl didn't want to be seen with a Bay*@#ner
Happy Whaling.

My 90 Johnson under warranty had a similar problem. The dealer said it was a porosity problem in one of the castings. I just called it a leak in the carburator with the fuel just pumping out the air inlet.

They fixed it. I only lost two weekends on the water. Engine runs fine now.

either a leak in a gas line that is sucking in air, or fule line is bad or fuel pump is going. No biggie!

Remove the spark arrestor again and pump the bulb, look to see if gas is leaking anywhere.
