I have a series 2, sometimes the engine seems to die down, then suddenly picks up. The car has been fully serviced, I did have problems prior to the service but was OK after, It seems like it is starved of fuel, the problem started a few weeks ago only a minor flat spot, but has increasingly got worse.
I recently topped up the carb dampers with engine oil sae 20 50 would this be a problem.

Tried switching fuel tanks when the problem occurs?

The in-tank pump filters often get partially blocked and cause fuel starvation. If it only happens on one side and picks up almost as soon as you switch over to the other tank then chances are that's what's wrong. Even if not it's well worth taking them both out and cleaning the gauze, because sooner or later you will almost certainly have a problem with the fine gauze mesh getting blocked.

Just make sure the tank really is empty before you remove the pump.....
