Re: what did you do to your motorized bicycle today?
Finally figured out what was causing my carb to leak. For background, I'm running a Mikuni pz19 vacuum carb on a 98cc flathead. Carb was leaking a little gas, not much, but it was leaving a nasty residue on the bottom of the carb. For awhile I thought it was leaking out around the vacuum hose, and I kept trying to stop it from there. Finally today I figured out it was leaking from the drain plug, which did not have a gasket (carb was given to me used for free). So I cut a thin piece of the vacuum hose off to attempt making a gasket for the drain plug. Lo and behold, it worked! Looks pretty good, too.
