DIS was caddy-olds and the buick v6

[Mika Helander]

What I don't like about implementation of the DIS systems (aftermarket ones) 
is that in cold weather country like Finland I'm living is that if engine 
must be turned at least one (in some cases two) rounds to fire cylinder 
first time in that case the battery voltage can be too low to turn engine or 
give enough fuel pressure or spark to start it!

I remember my brother's Opel Ascona 1.9L bored to 2.0L. He was in army, the 
ambient had been below -25C at least a week. Well, temp was -35C, he pushed 
throttle couple of times (at least two weeks from last start), turned the 
key and engine very slowly turned to first TDC and vola. Of course 
carbureted and having vacuum/points distributor...

I "feel" this turn-couple-of-crank-turns before my 350 TBI starts in cold 
weather...
