I ain't no complete idiot, but I must be when it comes to adjusting the idle speed on my 1970 250C..
I have the M130 engine with the dual 35/40 Inat carburetors, and although I have three lrepair manuals, all the photos are muddy and do not show clearly where the idle screw is located.
It sure must not be obvious from looking at the carbs.
Can anybody describe it to me, or send a really clear photo on this forum or off-line to my direct email :
