hi i have an 81 deloreanvin #990 last 3.. my fuel mixture is hit or miss i set the fuel pattern by backing off the mixture screw for the spray pattern it seems right but i smell gas in the oil and the oil mixture is turning grey. i have changed the oil 3 times paranoia.... people on this delorean forum speak of using a dwell meter for a final fine adjustment of fuel mixture could anyone explain how to do this and stop making bp richer..
p.s. this is regarding my 1981 delorean last 3 vin# 990
