Running Rich???

when i get ON IT (WOT) there is some BLACK smoke pouring out... wouldnt that pretty much mean im running my carb a little to rich??? or what???

Isnt that just UNBURNT Feul???

then if it is... that means my gas milage isnt the best and a little tuning can make it a lot better....

and would running it to rich cause it to not be 'as peppy".... yeah or no???

Running rich at WOT doesn't mean it's running rich at cruise, which is the main contributor to gas mileage.

Going WOT is bad for mileage even if it's operating at the perfect mixture ratio.

Would doing the secondary mod where they open up more provide more air lean it down some? I have the same problem...
