I took the carb off my mini (1981, 998cc) the other day to give it a bit of a service. Now I've put it back on, I can't get it to idle properly. It runs fine and sounds great with the vacuum advance disconnected, but as soon as I re-connect that, it cuts out. It only runs if I increase the idle speed or have the choke out, and then it sounds pretty rough.
The timing is OK, I checked that with a strobe, I just can't figure out what's wrong. Any suggestions?
Cheers,
Matt
