Re: [alfa] Throttle Sticking

["Gwynne W. Spencer" <gwynnes1@xxxxxxxxxxx>]

There are a number of plastics that make good "low speed" bearings.  Try 
any metal fabrication shop - they often have these plastics for use in 
making up assemblies that need a bearing for a metal shaft that is operated 
at low speed and load.

Take a look at: http://www.graphalloy.com/html/plastics.htm

What makes you think that I am not in the USA ??  I live in Punta Gorda, 
Florida, USA   I had a friend who worked in a machine shop and he had some 
Teflon sheeting for a job they were doing. I only needed small scraps.

The shaft that goes across the firewall rests in "rubber" blocks (Alfa P/N 
105.00.44.546.03) at each end, held in place by  formed metal brackets.

In my '65 Sprint GT, I also replaced the throttle spring with one that gave 
less tension. If that spring pulls very strongly, it aggravates the binding 
- look at the shaft in place and think about it.
