Why won't the Izh Jupiter 5 start? Is there any spark coming from gasoline?


Jupiter-5, help the teapot...

Greetings to all!

The motorcycle sat in a barn for 2.5 years... due to a dead piston...

I pulled it out, washed it, removed the head, cylinders, installed NEW ones: pistons, rings, spark plugs, high-voltage wires, all the gaskets that came along the way...

I collected everything in a pile, placed a car battery next to it, ran the wires, pumped up the carburetor with gasoline - the result was zero, it won’t start, it won’t even catch...

Attempt 2: put 2-3 drops of gasoline into the cylinders - 0 emotions. Attempt 3: we hooked a cable to mark 2 :), dragged 500 meters to the 2nd... byrk byrk byrk, doesn’t grab it..

We checked: the ignition was set according to the marks, the spark plugs gave an excellent spark when pulled with a cable while increasing the gas on the motorcycle, the byrk byrk was heard more clearly, so I believe that the carburetor is working.

Guys, what could be the problem? PS I myself have never disassembled or repaired motorcycles in my life... but in 2 days I kind of realized that there was nothing supernatural there.
