I detect a weird smell from the clutch...

Odors can come from a variety of sources, but one such source is the clutch. If you smell a burning metal odor, it could be your clutch slipping/burning. Do not allow the clutch pedal to sit in the middle of its range of travel for any length of time. Either engage or disengage the clutch quickly and smoothly, with a little "feathering" as the transition. Allowing the clutch to slip will lead to burning/glazing and premature wear - an extensive and costly repair.
