There are a lot of smart people on here.... to my shame, I'm too idle to become smart.
So, could some kind soul out there answer a question for me ?
I've got a 1991 3VD TDM 850 and want to know what the idle mixture screws do.
When you unscrew them do they admit more fuel or more air ?
As you'll know, they're bloody footer to access so I really would like to know what I'm doing before I interfere with them.
Thanks in anticipation.....
