For years I have had this problem. Changing the rope, renewing cracked bricks, cleaning everything out has just been wasting money and my time. I have the answer now and am so surprised no-one has got close to saying what we consumers should do!
So, get a torch. Get down on the floor. Look past the front long lever with a kind of paddle at the end that you push in and out to control the air flow, ignore the nut on that lever arm itself and find the hidden vertical bolt which is on a sprung washer and which is the mechanism that should hold the square paddle against the inlet holes! Mine needed many turns to tighten it up against the underneath of the unit. The paddle had obviously dropped down so that pushing the lever in and out had almost no effect at all - it was not tight against the inlet holes. Now it is like new. You must do this! Really!
