Quad Bike 110 for Children: Spark & Fuel Present, But Fails to Start - Possible Causes & Solutions

Hello. I'm new here, I'd like to test your skills. But seriously, I have a small problem with a small quad bike 110 for children :)

I bought it damaged. I checked everything, and here the problem begins, because the quad does not start even though there is a spark and fuel is coming :)

Checked :
-module
-Isystrator
-shaft condition
- cylinder condition
-the state of the rings
- the condition of the head
- I measured the compressions
-checked the timing
- second carburetor fitted
-fun
-candle

Well, what do you say, gentlemen? anyone have any ideas? I tried for a cake, it also does not speak

I suggested that I check the ignition switch, a friend had a similar problem in bashan 200, he checked all the electronics, there was a spark on the candle but it was weak, he replaced the ignition, the quad lit

The installation is done in a short time, the spark plug is 3 cables, modul, and the coil in the candle.

is the spark but weak ??

Try on another module of such a quad, I also repaired everything like a spark, fuel, timing and no smoking. It turned out that the ignition module was to blame for everything.
