Amal Carb

 This is a good site with a better lay out.

 Extract:  
Introduction
The purpose of this homepage is to explain the function of the most widely used carburetor in classic biking. A carburetor has been thoroughly modeled in Solid Works, a professional parametric solid modeling program, and the model has then been sectioned and rendered in PhotoWorks.
The idea is to make this site a dynamic source of information for rebuilding and troubleshooting of this simple and rugged carburetor that has received a somewhat bad -and unjust- reputation over the years.
I would therefore encourage anyone that would like to contribute to contact me with photos, info, tips and tricks. Full credit will be given to all contributors.
