[Roadsters] SU air filter to carb gaskets /very rough idle

[Roy Haslett]

I had the same problem on my 1600.  Car ran terribly.  I sprayed some carb cleaner around the intake while it was running and the idle increased, signaling a leak.  The gaskets between the carbs and intake had basically disintegrated.  Check there to see if that is your problem too.  The gaskets at the air cleaner should be there too for proper air flow once you have balanced the carbs.Good LuckRoy H.

I started my 2000 SU the other day after it's winter break and it ran so rough I thought it might bounce off the mounts.  As I peered around the carb area hoping to spot something odd (maybe a leaky hose causing a vacuum leak?), I noticed that I don't have gaskets between the air filter housing and the carbs.  Yikes.  First of all, I really wonder how this has been affecting things all along, but second I'm wondering how I might start correcting the rough idle.  Since the car has never had these gaskets since I've owned it, whatever is currently happening isn't exactly related (that is, it ran fairly smoothly last year).
Any thoughts on 1) the missing gaskets, and 2) a process of elimination to smooth out the idle.
Thanks everyone,
