here I am again, good evening everyone.
after changing the tire my spartamet no longer works. it floods a lot and loses gasoline.
I removed the carburetor and saw that gasoline comes out of the air intake. the air filter is full of petrol. I disassembled and thought about the pin that doesn't close well. but I checked and it closes well, in fact until I start the engine, it doesn't lose anything, the petrol stops. (I see it from the transparent tray).
Can some good Samaritan tell me what could have happened? until the tire change, my spartamet was a watch. I thought about the depressor but I don't know what to check. that electric wire that reaches the top of the carburetor what is it? petrol comes out copiously after a few hundred meters.
I thank so much who can help me, I am desperate.
