Exhaust. It's less smoke and more thick exhaust. I gotta do some house cleaning and then I'm off to reach myself how to tune a carb.

The wire part of my secondary metering rods was so screwed up it wouldn't bounce when the horn was attached. I had to re shape it to fit right. Looks like someone got to this carb before me and screwed it up.

Hahaha I fixed the leak at the pump but now its coming out of the gas cap. Jeeez I have no idea what's happening. I'm taking it to a friend to tune the carb. I can't seem to get to the mixture screws to save my life so I'll let him deal with it while I try to figure out my next move.
