[TR] Teflon washers in SU Carbs -The scoop

[HANS DEFERRANTE]

Hi Dennis and Randall,

I spoke with Walt from Britalia and this is the scoop and advise I got:
The green  o-rings are not teflon. They are actually made for the air  
conditioning  industry and are available from A.C. supply houses. As  
far as he is concerned they have no particular advantage over the  
neoprene o-rings such as available from Moss or hardware stores.
His recommendation was to polish the brass jet tube with rouge, tooth  
paste,  or polishing compound to a gloss and, if necessary, remove  
any visible blemishes with a rubbing compound. Lubricate the tube and  
washers with a thin layer of synthetic grease before installation.
I followed his advise and used the "Moss" washers and a grease with a  
high content of teflon (on the bottom gland washer as well), which  
did not to come off with gasoline.  It is a bit early to judge, but  
so far it has worked perfectly --- dry as a bone --- and the jet  
slides up and down very easily.

Dennis,  -- I have been trying to get a hold of a friend who had an  
A.C. business, to find out about those mysterious green washers and  
who is also an excellent mechanic. If he thinks it has some merit  
I'll get some for you too.

Hans
