Sorry but you ignorant combative style doesn't endear me to wanting to just give you simple answers although I already have...... Get to work.

Not true. Any time you have a richer than stoich mixture you have excess carbon. Go figure it out......Go through all the Shrinker files and piece it together.

1 Variable........

I'll say it again: I can change 1 variable and it will make the plugs read REALLY RICH when I haven't changed the AFR at all. The can go from Tan before to Black after and I haven't touched the carb. Its still metering the same Air and Fuel mixture but its now Rich.......Or is it?

If you did then you would understand that there's not enough for all the Carbons and Oxygen molecules to pair up. That means there's excess Carbon to find its way onto the plug. Lambda is different for different fuels. Using Lambda to Determine Air/Fuel Ratio The result of the calculation is...

You sure it wasn't because you like Turtles?

Don't need to. Its very well established in the field of Chemistry what Stoichiometry is. That's why there's different Lambdas for different fuels.......You can be on either side of stoich either rich or lean depending on the AFR of different fuels. You can give an engine a rich mixture and...

Where not talking about Lean mixtures looking Rich we're talking about Rich mixtures having excess Carbon to Air ratios which means there's not enough carbon to bond to the lack of oxygen. That means there's more Carbon than there is oxygen. If its not Rich enough around the plug at ignition...

Yeah but I have few different manifolds I can put on so I managed to find one to fit (portosonic) but the heads have been milled a bit to get from memory about 58 to 60 cc from the 302 closed chamber heads. You have to measure it to really know where you stand.

How can you not have free carbon if there isn't enough oxygen for it to bind to? Measuring Stoichiometric Combustion Processes In any combustion process, an amount of oxygen reacts with an amount of fuel. If the amount of oxygen exactly matches the amount of fuel, combustion is complete. This...

I've got a 318 with Enginetech pistons that measured 10 thou down after the block came to me heavily decked. Compression height for those pistons is 1.741 so if you calculate the distance with with the piston(1.741), rod(6.123) and crank stroke (3.31/2= 1.655) you get 9.519. If you go by...

But Larry and Bruce do......That's why they could do the **** they did. Knowledge......Its priceless when you have it...Others just call it plain old science.

Its called science....... What does that have to do with the established science......... Intelligent people learn from the best in the game.......

If you understood the basics of combustion and chemistry you would understand that any AFR below 14.7 would leave free carbons to find they're way onto the spark plug during combustion due to the heat and pressure generated at ignition time. Considering Bruce Robertson and Larry Widmer could...

What's the 5 gas telling you the gas balance is and what's the calculated AFR? What's the arc duration time and how smooth is it? What are you using to log the data from the pull?
