The filter was off, I was trying to start it and it wasn't firing so the carb filled up with gas and the float didn't shut it off so it flowed out the vents on the bowls, and sat on top of the manifold. I got it started and let it run for maybe 30seconds, and then I turned down the idle and it died. I tried to start it but the battery was too low and wouldn't crank it, so I spent about 2 minuits hooking up the truck to jump it, which gave the gas on the manifold time to heat up and start evaporating. when I started cranking the coil connection arked, which lit the fuel vapor, which lit the gas on the manifold. got it out with fire extinguisher, so no I have to clean up the powder mess. I found a rebuild kit at autozone for $28 so I guess I will get that. the bowl gasket was shrunken really bad, that may have had something to do with the fuel leak. after I got it started the leak went away, so I think the needle came unstuck and started working. I guess I will see!
