I sticked the floats up high to see if I had any leaks and nothing. So it’s definitely float/valve related
McCabe-Thiele (Ted):
Don't you mean you set them lower or do you mean if you pushed the floats up then it closed the valve ?
The lower the float height in the bowl the greater the leverage between the Tab and the float needle so it shuts off earlier?
When setting my float heights with the Carbs upside down the float Tab would be just touching the sprung part of the needle valve without depressing it. I then measured the gap between the Carb body and the bottom of the float that on mine were flat - as per NJ's pictures in her float height setting guide.
Looking at your upside down picture the spring clips look the wrong way up to me ? I'm an amature so listen to NJ.
Nurse Julie:
I can see by your photo #1 that the floats aren't level overall and # 2 from the left shows the float arm is bent as the floats are sitting at an angle. As far as the float tang is concerned, remove the floats and flatten the tang so it is flat, its got that hook effect to it at the moment. As Ted has just said, when the floats are fitted, you pull the tang up higher to reduce float height, and push it down further to increase float height. The floats are on the correct way up. The spring clips are the correct way up.

Alright after a day of fight. I can say it, no more overflow!
I had to raise some float to 23mm. I don’t know if some spring got more resistance or anything else but it works...
I’ve put everything back on try the spark and.... no spark, I’ve seen a live wire grounding from the electronic ignition... it might be blown inside now.
Reading on the coils after the plug caps is 5000ohms, weird. I have to investigate this now :-[ :-[ :-[

Well done on the carbs. Nothing worse than carbs with an Incontinence problem 😁😁😁😁
