[DML] Re: Fuel Metering

Exactly when did I ever "advocate that everyone should rip the
K-Jet off their car and put a carbureator"? Those words have *NEVER*
been written or spoken by me. I specifically stated in it, as I always have, that those who prefer forced injection should pursue those avenues. It would appear opinions or preconceived notions are overriding my particular words.

Every time this topic comes up, your reaction is quite visceral
against carburetion. I suspect you had bad experiences with it in the
past. For that, I am sorry. 

BTW: Your post praises Marc and Dave D. because they "they tell us
about it [DeLorean engineering alternatives] for our information" but
chastises me for doing the same. I consider that a double standard.

The simple fact remains: carburetion *IS* a viable fuel metering
method. You obviously do not like it, and for that reason alone should
not consider it. 

As we speak I am in direct conversation with yet another owner who
wants to try it for his DeLorean. As always intake manifolds are the
limiting factor. Jeff Friday was selling custom manifolds, but has
since gotten out of the business. In his absence I am pursuing the
possibility of modifying a 3.0/B280 manifold. Experimentation *IS*
part of the enjoyment of DeLorean ownership (just ask Marc or Dave D.).

Note also: Carburetion does not require "spending a large sum of
money." My conversion cost about $300.
