I just looked over the link provided,and the O2 percentages look awfully familiar.So do some of the others.So I guess that proves the military gave me some bad numbers.I'm new to computers and the net also,so I don't have the greatest luck trying to research info alot of the time.Thanks Jim for the info.I doubt if I could have found anything like it any time soon.
Don't know what kind of math formula to use with that to figure out percentages.You'd have to know intake cfm also to complete the formula.But it seems like there's no more then maybe 5% max unburned fuel at operating temp.

Okay.This leaves me confused with some of my own personal experiences.Craig,you seem to know the most on these formulas and their applications.But anyone else who knows or has good ideas on the subject,please feel free to help out here.

Here's my personal experience in building a vapor carb from plans for someone else.First the car.1978 Pinto 2.3L,4 speed manual trans.stock gearing with 185/75R14 tires replacing the stock 155/80R13's.Vapor carb on stock intake.Timing set back to only 2 degrees advance.More caused preignition.Spark plugs 2 steps cooler then stock.The engine compression tested at 112lbs lowest,and 119lbs highest before being changed.We ended up getting an average of 60mpg during the 4,000 miles it was driven before it died from tarry residues gumming up the valves and rings.
I don't know many spacifics on the others I mentioned before,like I do with this car.

But it now seems pretty obvious that combustion efficiency isn't the major factor here I thought it was.I know the tire change could have gained us about 5 mpg better then stock.But the rest now has me confused.I'm going to try figuring some of this out.With the cooler plugs nessacary,we obviously had higher combustion temps.Being limited to 2 degrees advance leads me to believe we had both better and faster combustion.And with less advance required,we had less power loss on the compression stroke.Because the early spark starts trying to force the piston back down sooner.But could these changes have made that much of a difference?Or is there something here I'm missing yet.Stock mpg on these Pintos was 25.I got 35 mpg on mine with larger tires and better ignition.So you can use these for baseline comparison.

I should probably explain that all my books and manuals I used to have,military and otherwise were stolen 10 years ago.And my educated guesses and beliefs are based on what I remember studying,and my 24 years experience as a mechanic.Sorry,but it's the best I can do for now.
