Back when I had a nasty flat spot on my Moto Guzzi Monza I bought this book to sort it out.

It’s about their motorcycle carbs, but it unlocked the previous black magic voodoo of carburetion for me. The DRLAs were relatively easy to understand once I understood how a carburetor works.
Spoiler Alert: Carbs suck and FI blows.
eta: There’s also a good bit of DHLA info on the interwebs due to their popularity on Brit 4 cylinders. Pretty much everything transfers.
