Tohatsu 50D2 Idling issue - part 2 Video included

Hi Everyone,
This one is breaking my heart so I am appealing for more help.
Engine struggles to idle and appears to misfire
Done so far
1. All new plugs
2. All carbs and fuel pump dismantled and carefully cleaned
3. Fuel lines checked. Fuel filter stripped and cleaned
4. New fuel

I am beginning to suspect coils, timing etc., but would appreciate guidance as to what I should tackle next. Any advice much appreciated

Video isn't working for me but I would suggest checking the coils, the engine should idle ok with basically any timing setting you can get on the tohatsu. You can run tohatsu 70 coils, they're even allowed in the racing regs. No performance upgrade just reliability

Roflhat, thanks for the advice. Stripped ignition coils and found one with a crack on the side. Picked up a good spare. Ran tap through bolt threads and cleaned all terminals for better ground. Put elec protective grease on all connections. Followed chapter 5 in the service manual to the letter and reset all carbs, linkages, idle. Ran the motor and she is sweet as a die now. Thanks for advice.
