    As I was comeing home through my apt. complex I drove over the speed bumps a little faster than normal, but still only about 15 mph tops. On the last one my engine started running really rough. Imediatly after I hit the bump it started stubling and idleing rough. What did I do to her? Something in the q jet? I just rebuilt it about a month or two back and have hit plenty worse bumps since. Maybe a sparky plug wire? I opened the hood and looked around, but nothing obvious. Let me know asap please.

    Check for a burned plug wire, broken dist cap...... stuff like that. Maybe you knocked the timing off.

    I checked all the wires, and they are all on. Its running really rich though. I can smell the unburnt fuel out the back. Is there anything in the carb (i.e. metering rod or something) that would cause it to do this? I'm going to go check the cap real quick and make sure its not cracked or anything weird like that. I'll let yall know if I find anything. Thanks again.

    vvvvvvaaaaaaaaccccccuuuuuummmmmeeeeee leak-for sure! be very carefull and spray carb and choke cleaner all around the intake and carb and any emmissions lines you may have, as soon as that baby revs up you found you problem (avoid the distributor for obvious reasons) one of the only repairs you can do with a stiff drink in one hand-hey its friday night.

    Your carb's float may have got stuck. Try tapping on the carb with a screwdriver handle above the fuel bowl. Sometimes that'll free it up again without having to dis-assemble it.

    I called it quits for tonight a long time ago, but I have to go somewhere tomorrow so I will have to get up earl. I think the float got stuck, or something is makeing a weak connection in the ignition system. I'll figure it out tomorrow and tell you all what it is.

    I figured it out. Took me a couple of hours to fix it early today. Some how the spot where the spark plug connects and where the rotor conncects on the inside of the cap came apart. Visualy they looked fine, but there was no connection being made on two of the posts on the cap. I figured this out after I had take the carb half way apart and put it back together. GRRRR! Oh well, shes pering like a kitten again. Dont ask how I figured out something that strange, its a sore subject. Thanks to evryone who helped me in the CR last night.
