Dear hyper milers
I forgot to write that to test the screw setting what u can do is do a pre spark plug inspection and post spark plug inspection to see if the leaning out is working.Also closing off some of the more fancier vacuum lines that u deem unnecessary will help in performance.
Another test I use to check if the leaning out op was a success is first I clean the exhaust pipe outlet and look at what I have cleaned out before and after,if u did it correctly u will notice a noticable reduction in soot and water vapour or water droplets emerging and definite reduction in noxious smell.
Another thing I forgot to mention is that when a carb is wasting fuel the unburnt fuel enters the oil in the form of carbon and as fuel itself which in turn makes the oil dirty and the dangerous problem is it makes the engine oil thinner.I have had people complain of oil level increasing even thou there is no leak from the fuel pump to the engine.The thin oil easily enters the burn chamber and messes with the spark plug and u have more dangerous emmisions.
Another successful mod I tried on double carbs is I turned off the second carb[not for v8s because they have power needs] will send details
