Nearly there.

After having trouble tuning the Webers I have installed the factory correct and genuine needle and seats being 1.5 and adjusted the float levels being 5mm to 11.5mm.
The fellow in Sydney who rebuilt the Webers used Fuel miser brand 1.75 needle and seats and had the float levels set at 5mm to 17.5mm.
I put it all back together today and fitted the new Flamethrower 3ohm-40,000v coil to assist with the new electronic ignition. There is no doubt it is running better however it is still "hunting" at about 5000rpm when cruising. I think it is still running lean at this rpm.

Correct Weber made needle and seat on right. 1.50.

Adjusting the float levels.
