Hi Norm, I'm in the process of modifying a G4 carby and have a few questions asking for more details.

With the 3 washers, are they used as a nut for the adjusting bolt on the cap or a spacer for the poppet valve?

Do I need to use 3 washers to equal 1.6mm or will a single (or pair) 1.6mm washer do the same thing?

What did you use to secure the nut to the outside of the cap?

Does this modification mean there is no longer a need for the throttle cable as it looks like that second screw will block it's location.

Cheers
