Ok, this sounds totally ridiculous and I've been working on french mopeds almost exclusively for as long as i've been involved with the gang... but I got this 7.
Cleaned the points, put on a new hi coil, got some good blue consistent spark.
Then I cleaned out the carb and started it up. It runs very nicely for about a minute and then it shuts off and gas starts pouring out of some magical part of the carb that I can't find. I seriously can't find it!!! I've temporarily plugged all of the overflow holes and I put a new float in it (the float is identical to the old float, only this one "floats"). If I blow through the gas intake and then plug up the float pin stop with the float pin, i can't blow through it. This leads me to believe that the float would work with gas in the carb.
I've cleaned every possible surface inside and out and i've tightened down everything that I can find a leak from. I even got a new float bowl gasket just incase.
Are these gurtners for the 7 just pieces of shit? It would be very hard to fit a dellorto on it, considering the limited space under the frame.
