Re: [Amc-list] Holley Carb Questions .... Holley Mile Dial System &/or Percy's Adjust-a-jet?

[greg_taylor@xxxxxxxxxxxxxx]

Hi Mark,
Thanks for the feedback.  I previously monkeyed with 2 different crude 
prototype Hydrogen generators on my 1989 Grand Wagoneer and before the PCV 
unit developed a leak, I gained about 4+ MPG's for a partial tank of gas. 
I'm on the watercar yahoo group and they are working on some different 
designs for the generators that seem to be much more promising.

Anyhow, I just spoke with Holley Tech and the Mile Dial system is 
adjustable about 10 jet sizes, with the minimum being the current main jet 
size.  I'd need a 50 jet, if I wanted to adjust between 50-60.  Also, the 
bowl gaskets are no longer available for the Mile Dial bowls (different 
than std holley bowls), so I think I will shy away from that system. 
Perhaps the Percy's system will be better.

Yahoo has a group called wastewatts that has been beating the hydrogen 
issue to death recently.
You may want to read up on it. They say it is energy neutral or even 
negative, as in it takes more energy to create then it produces! 
  I don't know.
 Whatever you do remember, it's all in the mixture.
too lean, is too lean and won't help fuel mileage.
I'd put an O2 gauge in it to keep and eye on things while tuning.
I believe those kits you mentioned work, they just did not sell well to 
performance guys...
