Having had several scooters I decided I wanted a moped next. I picked up a '79 Motobecane 50V on craigslist for $50 and got it running with just a new plug. It's pretty pokey and had been sitting unridden for an unknown amount of time so I decided to clean the carb. It has a Gurtner carb. I have gotten something wrong because it now leaks gas out the throat, ino the air filter.
What I am wondering is a couple things. The float has a shaft through it that has a point on one end. Does the point go up or down? Is the hole/tube at the top of the bowl that the float goes into just a vent to atmosphere?
Also, there is an o-ring under the float bowl lid. Where does this fit in relation to the paper gasket?
Lastly, the choke cable was gone so I used a generic one. I didn't know which way the brass part should go. One end is slightly smaller diameter than the other. Does the small part go up or down? And, when the choke lever is pulled, should the choke in the carb throat be fully open?
I looked at the manuals from mopedrider.org but they are not specific in these matters.
Anyway, thanks for any pointers.
