Hi,
We have a problem with one of our minis. From 5500 rpm it runs bad. It looks like ignition can't handle the high rpm. The problem wasn't there before, it was running well with this setup. It's a NA 1340 with Sidedraft Webber and aldon ignition (points) Everything in ignition area is renewed (points, rotor, cap, spark plugs, spark cables). Car was a few months adjusted ago on rolling road.
Has anyone any ideas what to check?
Regards,
Remko

Check that all electrical connections are a tight fit. Mine came loose once on my 1330cc and it run like a bag of crap. Only found this out when i knocked it with my hand with the engine running. :)

OK thanks! We'll do the electrical checks again and we are going to install a lambda-sensor to check the mixture. We'll keep you informed!
