Hi. A lot of lawn equipment came with primer setups. You might check with a local shop, you might get lucky and connect with a parts guy who is willing to search his stock for one that might fit. If you can come up with rough dimensions from the old one it will help. BTW, I have a bikebug. It's one of the older ones with a fuel pump, so it doesn't need a primer bulb. Mine has a small Keihin carburetor-looks like a 10mm. What does yours have? I need to clean my fuel tank with vinegar and install a new in-tank filter before I can run it, but with good compression and good spark, it should fire right up.
