Re: [DML] RE: Strange acceleration problem



There are two different weights in the distributor. One has extra metal spot
welded to it to make it heavier. Make sure you get the right spring on the
lighter weight only. I tried playing with a B27 distributor and drove with
it from Minnesota to Houston for the open house this summer. That
distributor has equal weights using two springs. An increase in torque was
noticable but the car felt slower. The engine didn't move up the RPM range
as quickly so I re-installed the stock distributor on my return home. I
called all over the Twin City area looking for someone that still has a
machine to measure the advance curve but couldn't find one. New cars
ignition advance is controlled by the computer and engine shops doing older
engines now buy distributors already set up from Mallory and others. I'm
guessing the single spring set up is unique to the DeLorean version of the
B28.
