Re Amal 375/7
Just did a buy it now.
The carb fitted to my Dragonfly is 375/6 25/32".
Only 1/32" smaller, and I suppose that would have only made a difference on full throttle, and with the miles of induction pipe to the cylinders perhaps wouldn't have made any difference. Anyway I'll be happier with 375/7 13/16".
Thanks for the tip off Red.
It will be one less frustration, of the many weird things that have been done to this bike.
