Sometimes when i turn of my Mini it shakes a bit and the ignition light flutters. Im pretty new to Mini's and was just wondering if this is normal with the A Series engine and if there was anyway of stopping it.

Many thanks

no its whats called running on but it can be caused by stale fuel, how olds your fuel?

just lift the clutch up a bit as you turn the key

air/fuel mixture could be out

Leaving the choke on? Not the best thing to do, even by accident.

I take it you're talking about run-on issues.
Before stopping, put it in gear, push the brakes and slowly depress clutch as you turn the engine off, this is a good 'work around' to the problem.
A decoke to the cylinder head may cure the problem, which can be caused by wrong mixture/ingition.
Even a modified cylinder head with 'hot spots' on the chambers may cause the problem.

.............so its still got fuel in the carb

It should always have fuel in the carb

You mean lift the clutch. Depress = press.

Yep!!
Sorry for confusion..

Does it matter if they run on tho a little, is there actually any adverse effects to the engine, apart from making you look a little silly.

I think mine has an anti-run-on vale that dumps loads of air into the bores when its turned off to dilute the remaining fuel and air.

i had this it was pre ignition as the timing was slightly out

If it's an SPi injection engine then it could be one of the vacuum hoses leaking.

Or if it's a carburettor engine then make sure the choke linkeage on the carburetor isn't sticking, mine did and this caused the idle to be too high. This caused it to run on (making the Mini engine shake the way you described).
