Ive tried to reverse engineer a circuit board for coil ignition testing but it was covered mostly in glue and i could not see all the paths on the board.

then i tried asking google AI to recreate the circuit from the drawings ive made. (i tried to make it in KiCad)

And i asked ChatGPT for help and made this Circuit(s)
I noticed that Chatgpt connected the 2nd pin from the potentiometer (wiper) to nothing. (made more mistakes as i asked to fix something)
i got BD139 instead of BC286 because i could not find it for sale, also the BU931ZP i got BU931P.
Is it possible to make it simpler and working?

Take out diode, connected parallel to coil, else you never will get spark.
Look at this schematic:
