    Priming 951's / XPL after filter clean

    Hi all,

    Just wondering how you guys prime your 951's after you have emptied out the water and fuel separator?

    Emptied mine on the weekend and it took a fair freaking while for it to start again.... Also when it did start it ran rough for the first bit.

    Cheers,

    Chris

    pump the trottle many times then crank it, this will make the accelerator pump prime the fuel
    but its normal for it to stall and cough, just let it run for a bit, until all of the air is out
    of the fuel lines.

    Chris, you can prime any fuel system by removing the return fuel line off the carbs that go back to the tank. Plug it with a #2 phillips and tighten the clamp. Then remove the gas cap and wrap a rag around your air hose and slightly pressurize the tank until fuel comes out of the barb on the carbs. Catch excess with a jar or rag. Reinstall the hose and the carbs are fully primed.

    Thanks,Rob, you're the man when it comes to doing something the right way, lol
    I (sometimes) half ass things and go the easy way,
    like turning it WOT until it cranks, I've never really primed an engine.

    Your method works great after the carbs are primed, I do that on mine every time I cold start it. But if the carbs are dry after a cleaning, the engine still has to turn over many times to pump the fuel in, to fill them. Another shortcut is to pull the spark plugs out...the engine turns over faster and fills the carbs quicker.

    It never takes mine more than about 18-20 seconds of cranking (at ten second intervals, no need to burn up a starter) to fill the bowl back up.

    I have not had to prime a 947 ever.

    Though, if you do, Robert's way is the best.

    The easiest way is to just remove the return line hose and blow through it until fuel comes back out of the return line carby fitting then the carbs are full of fuel.
    Make sure the fuel selector valve is on as you will be blowing all day.

    I agree. I used to do it the my old way until Shooter came up with your way. I just forgot and typed the old way...
