There are some carbs that have three adjustments, to eliminate lean conditions,
I read somewhere in one of the build threads, they are impossible to get now,
buying them NOS off ebay does not work, for one of the adjustments is concelaed,
and looking at the carb wont tell which carb is which, they had the same number
as it was upgraded but not marked as such, they came OEM on some saw, but
again, buy that saw, and you could still end up with the non modded carb.
The code is important, or nothing in the MT would work, if you could alter
the code you could alter the saws performance, more fuel means more speed
up to where the intake cant provide enough air, or some other bottle neck gets
in the way, I would like to see the code, as seeing it would reveal how the system works.
Even changing the language used can make differences, do we know what language
is used in MT, is it compiled or simple scripts, makes a big difference.
But yes, I do get what you are saying.
