There are probably a few replacement carbs to be found for your bike if you cannot locate the exact one. |
That was super helpful. To answer the question:
1P39MB
1P = one cylinder, "pair valve horizontal engine"
39 = piston size
MB = 50cc
I'm leaning toward attempting to repair the one I have in the scooter instead of replacing it. To that end, I bought a set main jets and idle jets. The float valve has some corrosion on the tip, but I'm not sure what the replacement would be. The float bowl gasket appears that it all fits in the groove and the broken ends line up nicely. Maybe a dab of gasket maker there would work.
I figure if I don't succeed there, I'll replace it.
