    RE: Walbro carb rebuild

    Take out both needles, and take off both covers, Try not to bend the lever that operates the inlet needle......Remove the fine screen and blow it out with some carb cleaner, and replace..Find the gasket with the big hole in the middle, put it on the carb on the side with the lever and inlet needle..Put the diaphragm with the metal piece in the center on top of the gasket, replace the cover...Put the other diaphragm on the carb, put the gasket on top, replace the cover...Replace the needles, open 2 turns from closed..Start the engine, let it warm up a little, then open the throttle wide and lean out the high speed needle until it just starts to slow down, open about 1/4 turn..Close the throttle to the idle speed you want, usually around 1800 rpm..Slowly close the low speed needle until the engine starts to speed up..Open the throttle fast..If the engine doesn't die close the low speed needle about 1/4 turn and open it fast again..Do this a few times until the engine dies when you open the throttle...Open the low speed needle about 1/4 turn, it should now transition smoothly..Go back and re set the high speed needle..
    There are always people who will say they never touched the "factory" setting...This is ridiculous, no one can possibly predict what the best setting will be...NEEDLES ARE THERE TO BE ADJUSTED.....[8D]

    RCIGN1,

    Thanks for the great info. It took all of 15 min. to rebuild. I'll adjust the needles tomorrow. To bad auto carbs can't be this simple.

    RE: Walbro carb rebuild

    On the same subject, I have a G38 carb that needs a rebuild, it isnt pumping fuel properly after sitting for over a year. Where do I find the carb number so I can get the right kit?

    The number is stamped in the body...The WTA6 with no choke uses the D10WTA kit, the one with a choke is WT338, kit is D10WAT...About $5...
