[TR] Teflon washers in SU Carbs

[Hans de Ferrante]

Re: 1961 TR3a with S U, type H6 carbs.
I heard during a TR gathering, that there are teflon washers available  
in lieu of the old cork or neoprene cup washers that seal the jet. It  
seems that the  leaky carbs with the consequential gas (sorry, petrol)  
smelly garages and sometimes houses is quite a common complaint. I  
have tried soaking the cork washers in oil as long as 3 days, but it  
helped only temporarily; the neoprene washers helped but made the  
choke hard to operate. Could not find anything in the Moss or Victoria  
catalogs or on line, other than that they were standard on the later  
types and probably not the same.
Has anyone ever tried these and with what results?

Thanks,
