    Help, just opened my first carburetor on Polaris slt 750, screw stripped out!!!!!

    Yeah, finally got the carbs out, opened the diaphram, and one screw was already stripped and the other is trying to. I want to just put it back together because they were running good. Only changing fuel pump but they said to rebuild carb. What to do? Its my first rebuild.Click image for larger version.

    I used some of the Craftsman screw extractors on a set I tore down last week. I think they call it a grabit. You put the drill in reverse and it cuts into the screw head hopefully grabbing it enough to break it free and have it screw out. That didnt even work for me so I ended up drilling off the screw head, and then I could get the screw out of the carb body with a pair of needle nose pliers. I have done it this way with a few mikuni carbs. I then replace the screws with stainless allen head screws. An easy out probably wont work on those screws, they are very soft.

    I have used Grabit on SEVERAL things, including rideplate screws, and they have always pulled it out, you use one end to drill the head the other end to reverse screw. used them on Car intake bolts, tons of things. AWESOME little tools

    Its a 4mm by either 12 or 15 mm length. The 12 mm might be long enough, or you would have to cut down the 15mm screw.

    I had the same problem with mine. I just used a centre punch and small hammer and it came out effortlessly, even though it looked like it was going to be a pita. I then cut slots in the heads and re-used them with a flat blade screwdriver.

    The clear plastic flap on the high pressure check valve. Does it matter if it doesnt lay perfectly flat? Mine has the slightest curl on the very corner. I'll include a picture but its hard to capture clear. I'm not sure what it does.[ATTACH=CONFIG]295683

    It needs to be perfectly flat.
