Hey guys - I've been scouring the internets for Dellorto 48 DHLA diagrams and I can't come up with ****.

All i want to do is adjust the idle! I think i'm messing with the throttle something-or-other.

Anyone have a diagram that simply labels what the adjustment screws do? I dont need the diagram that breaks it down with letter labels explaining which gaskets i need for a rebuild. Just the surface level diagram.

Thanks in advance!

if I recall correctly ....

the throttle stop pretty much doubled as idle speed adjustment. idle mixture was handled by the mixture screws on top - one on each barrel.

First Diagram: #6 is your idle mixture adjustment and idle speed is adjusted via the throttle stop screw. Backing the screws out richen the mixture, screwing in leans.

OK so that explains why some diagrams label it as idle adjust and some as throttle adjust. That clears up my confusion.

Thank you much! Of course just as soon as I get this thing running I'll swap it out for EFI. Meh oh well
