<VV> Re:ENRICHMENT NEEDLE long again

[N2VZD at aol.com]

somewhere years ago i got into playing with those needles. i used to have a 
source from rochester carb engineering. i made them lighter by grinding to get 
more pep.. but when playing with the power circuit you have to play with 
distributor at the same time. i still have my old distrib machine here waiting for 
me to go thru the electronics which have deteriorated badly. i run late carbs 
of some kind on all of my vairs.if you make that needle too heavy you get a 
weird stumble on accelaration(powerglide) i may even be able to find my notes on 
them somewhere.  vega and something else had that needle.  there were about 8 
or 10 different needles made by rochester .some were even made of aluminum. i 
used to know how much weight you could put in before you comepletely disabled 
the circuit by being too heavy.you could see the difference in a moto 
meter(vac gauge). was not much. i played with every aspect of carbs /distributors 
over the years you could.  they sent me a big box of roch parts for christmas at 
work once because of all the stuff i did and reported on.  gold mine of jets , 
floats, and 4bbl rods etc and such.   wish i was back there...  regards, tim
