My Sprite has started instantly and run well since I bought it a couple months ago, but idled rough. A spark plug reading showed that she was definitely running rich, but after seeing a lot of negative SU comments online (touchy, troublesome, takes a delicate hand to adjust, etc.), I was hesitant to start fiddling with my carbs.
Well curiosity got the better of me, and I start tinkering. Syncro, needle adjustment, another syncro and idle speed adjustment and I was done. Maybe 25 minutes, including time to read the shop manual. The idle is much smoother now, and the exhaust is much cleaner, based on my unscientific sniff test.
And, not to get too carried away, but this may be the best- starting carbureted car that I've ever owned. Pull the choke, pump the gas, and she starts.
Why the hate for these carbs? Not only do they work well, they look cool!
