I've been coming along pretty nicely with my first Mini, a basket-case 1989 Mini 1000 imported from Japan. I've progressed to the point that the car starts, runs and idles with good oil pressure and coolant temperature. Unfortunately this is the first SU carburetor I've ever dealt with, so I've been learning as I go along far as tuning is concerned.
When I started with this Mini, it would barely run at all. I've adjusted the mixture so it will start without the aid of starting fluid, although it runs extremely rough when cold (even with choke), will eventually idle on its own without choke but falls flat on its face under load.
- I've ensured the dashpot is full with the correct oil
- Ensured that the piston rises and falls smoothly with a "click"
- Adjusted the mixture significantly richer which is getting it to run, just not all that well. Intermittent rough idle and sputters out under load, and often just when giving it throttle while stationary. Hesitant to keep enrichening the mixture since other issues appear to be at play.
Here is a video of the current condition:
I've been trying to determine if it's an air leak somewhere, but have not had success as of yet. There is a missing vacuum line that was torn and disconnected when I took delivery of the car, and I have not been able to determine its actual routing.
