Hey there,
The clutch smell is prob just the bedding in period, is it still smelling after some miles?
the problem your having with 1st and 2nd could be that whoever fitted your clutch has neglected to
properly re-align the gear linkage..
with 3rd, 4th and 5th ok but 1st and 2nd playing up it sounds like the linkage is of-set too far one way..
might be worth taking your car back, explain your gear selection probs and ask them to check the gear linkage alignment..
hope this helps :@)
