what about the last number on them?

Wow, I didn't know each model had different numbers in the carbs. I've got two puchs that are both missing main jets (just got the bikes). I was gonna buy a whole set of jets and try them all out in the bikes, but now I don't have to do that. You've inadvertently helped me a lot. Thanks Zippy! Oh, by the way, do you know why the luxe has a smaller jet than the maxi? Do you know what the other differences are between maxis and maxi luxes?

My guess would be the Maxi Luxe with the Hi-Torque engine delivers a higher compression in the combustion chamber, so requires less gas (smaller jet #58) to produce the same power as the Maxi with a larger jet (#64) thus the better gas mileage on the Luxe.

To obtain the 2HP output on the Maxi's lower compression engine, Puch used a larger jet #64 to provide a richer mixture in the combustion chamber. Not as efficient as the Hi-Torque.

Thanks for the data, but my feeling is that there has to be more to ot than just the jet size. These numbers are cast into the carburetor body Also, there is usually an optimum jet size for a carburetor configuration. Even though the minimum dimension is 12 mm, maybe the throat contour is different in the various carburetors.

Here is some additional data from a Murray catalog. Murray is just another label for a Puch Maxi.

1/14/164 1.5 hp main jet 52/50

1/14/163 2.0 hp main jet 68/66

Sounds like you have a Chinese clone Bing carb.
