I did quite some trial and error with the idle jets and screw, and no matter what, the screw had to be 1 1/4 to 1 1/2 out for the setup to run right. I just discarded the 3/4 turn out setting for the idle as something impossible to achieve and am happy ever since.
That 3/4 setting was probably reached by someone about 40 years ago as the ideal. Well guys, if it is the carbs which are manufactured differently ( probably) or because of the global warming (less so), the setting is best at 1 1/4 out or even more.
Good to know that there is a modified mechanical dimension which may explain this and justify the new idle screw setting.
