My float sync instructions said 9/16"(14mm) from the top of the sync block to the fuel level in the tube.

Keep adjusting until that level is obtained or it will not idle/run correctly.

More bending?

This is 23mm measured from the bottom of the lids fown. Want me to keep bending?

I take a 14mm hex head bolt and lay it on the sync block and adjust until the fuel in the "straw" is level with the bolt head.

Bend until that level is reached.

You sure thats the measurement? More bending then? What happens if i leave it as it is? Problems while idling in traffic?

I read the instruction, you should have these instructions too if you have the sync kit.

"More bending?" I have no idea as you don't show the measurement.

"Leave as is?" I have no idea, you have to decide.

"Problems?" I have no idea, There is a lot more to the car than just a float adjustment.

In case you lost your instructions.....

I had to readjust the front carb float to 12mm as it was spilling fuel. Testing the car today.

I guess i must be somehow lean at 12mm on the front carb as today when accelerating on 3rd gear i started loosing power. I even had to open the choke to richen the mixture. Im about to change the fuel filter also. Do you concur?
