I have an '89 Javelin Fish 'n Ski with a Johnson 110 that sat for a very long time with bad fuel. I removed, dismantled, and cleaned the carbs out, and it runs great - as long as you're pumping the primer bulb on the fuel line. Here's a quick history of what I've done so far:<br />* Carburators removed, dismantled, soaked overnight in laquer thinner. Got a TON of junk out of them. Every part is perfectly clean, every passage clean. <br />* Emptied fuel tank of bad fuel, blew out all lines. Replaced with fresh fuel. <br />* New plugs.<br /><br />Ran with muffs for testing, then took it to the lake. Tied off near the dock, and ran it for 15 minutes or so. The longer it ran, the better it ran, but I had to keep pumping the primer bulb to keep it running. When I stopped, the engine would slow down, the bulb would go soft, and the engine would die. <br />If you disconnect the fuel line after the pump, it squirts fuel when the starter is cranked for a few seconds.<br />And now, I'm stuck. <br />Any advice would be GREATLY appreciated. <br /><br />Thanks!<br /><br />Jack
