Carb tuning, larger accelerator pump nozzle?

Rat,
So now the story changes AGAIN between post 77 & 80. And your calling me a dumb ***.....
And as far as 'haven't tuned anything' , I was fitting twin 35 mm Dellortos to my Knuckle Head Harley in 1967. Probably before you were born.
You don't know what you are taking about; typical of those with little actual knowledge, start name calling when they get caught out because that is the best they have got...

Yep, because you are such a pip, I’ll say it again. A bigger MAB will start the mains sooner in most cases and make the fuel curve leaner at higher rpm. It’s not that hard, but all the nonsense you vomit out caused me to get my thoughts out of order. I’ve corrected it several times just for you because you are so special. A bigger MAB will start the mains sooner. Did you get that yet??? When quoting Ulrich, don’t forget he is another one of many authors who tell people to use the wrong power valve because either they don’t understand how it works or they don’t care. It’s the same thing with the MAB and you just don’t get it. A bigger MAB will start the mains sooner and lean the fuel curve at higher rpm. A smaller MAB will delay the start of the mains and make the fuel curve richer at rpm. Did you get it yet? Has my redundancy helped your comprehension. A bigger MAB will start the mains sooner. There you go.
