I agree completely with Martyn, it is because you are slipping your clutch that it is burning and smelling, and WILL be doing it absolutely no good whatsoever.
If you think about it, the flywheel is rotating at engine speed,say 1500 revs per min, and you are sliding a composite disc against a spinning metal ring, rubbing the two together, just like rubbing two sticks together,eventually you will get fire.
Perhaps the cost of a motor mover of some kind would be offset by the cost of having a breakdown away from home, and having to have a new clutch fitted, at not inconsiderable cost.
