Starting on the first crank has almost nothing to do with the ignition. Both 
types of ignitions will do this if the fuel is there.

I think Russ's '71 sat for many years, so his example really isn't fair. OTOH, 
we hear of many Pertronix failures within 3 years, which is much less than my 
points last.

The automotive engineers aren't wrong, but we should not assume that the 
Pertronix is designed and built to the same standards as a product that Ford or 
GM will have to stand behind for 100,000 miles. That's an entirely different 
animal.

How long have you had yours and how many miles do you have on it?

There was a time when the 009 was considered the dist of choice. That time was 
when the stock dist was a vac adv dist. A mech adv dist was needed when people 
started putting different carbs on their VWs, because once you do this your OE 
vac adv dist won't work correctly any more. Around 1970 VW started supplying 
dists that had mech adv (for proper operation & power) plus vac adv (for 
enhanced advance at low load to give fuel economy.) These distributors are 
actually pretty good choices, but you really have to look at the specific 
advance curves to see which ones are better. It just happens that the early FI 
type 3 dists have very good advance curves, good for ANY aircooled VW engine.

There is also the thought that recent production of the 009 dists in Brazil is 
not of the same quality as the originals, but I really don't know if there's 
any truth in that. As far as I can tell, however, the only thing keeping the 
009 alive is the herd mentality that keeps people following what everyone else 
is doing. This mentality continues to be stroked by those who stand to profit 
from sales of the 009s.

Frankly, my first choice in ignitions are the old CDI units made by Delta. They 
use the stock points & coil and have a switch that allows them to be switched 
back to normal. I've been using them since 1966 and have had excellent 
operation out of them. My points last for many years with this system, and the 
only way they fail is if the little wire breaks inside its insulation.
