    Hi all.

    Is it ok to make your own gaskets for the fuel bowls on the carbs?

    One of mine was obliterated by a foreign object the last time PO put them together.

    I have the same thickness (pretty sure) gasket material onhand.

    It wont throw off measuring float levels will it...read somewhere +_ 1mm is vital.

    i don't see why not, a thinner or thicker gasket would move the bowl but the fuel level is what counts

    I need to make a gasket for the crank case cover. How do I cut it to match the inside shape? I can trace the outer shape to get that one, but, I am stumped about the inner one.

    And, what should i use for gasket material? Paper? cardstock? Cork?

    Or should I just use Yamabond?

    What I do is I cut the outside shape then tape it to the piece I'm making it for. Once that is done, I take the handle end of a screwdriver and rub it over the interior contours. The process creates an imprint on the opposite (facing down) side that I can then cut around to complete the gasket.

    I'd recommend gasket material with some RTV to ensure a good seal.

    i like inking the flange and "stamping" the paper. cut it out, soak it with hi-tack and bolt it up. it wont leak...ever!

    I tap the insides lightly with a ballpeen hammer. It leaves a clear impression to follow. Another option is to use carbon paper and tap the pattern.
    Do not use paper, it will leak. Use purpose made gasket material.
    This is a good question. Permatex makes an extensive line of gasket makers and gasket sealants. I'm sure some of them would work well but I'd suggest you do a little reading on their website.

    I've always made my own gaskets whenevr possible. I usually use an old cereal box to make them (Cherios, Wheaties, etc.) and it works well for me.
    I use water color paint on the original parts to stamp the pattern onto the cardboard, and cut it out with a razor knife. I almost always use RTV gasket silicone to seal things up when re-mounting the parts. So far, I've had great success doing it this way. >PD<
