Conversion to Mallory Distributor

["KENNETH A. vonKLUCK" <KAVONKLU@defrees.com>]

We have installed a new Mallory dual point distributor on my 1963 TR-4.  The 
engine has Type H6 S.U. carburetors.  The Mallory does not have a vacuum 
advance.  I assume that I should plug the hole on the front carburetor where 
the vacuum line would otherwise be connected.  Can anyone who has this setup 
please give me the benefit of their experience and advice.  Also please share 
any experience with the advance curve spring kit that is available for this 
distributor.
