Stiff clutch lever after Lever change?

[Tubz1983]

Tryed to swap the lever for an after market but only the brake fits, anyhow i took off the Clutch lever intially before i realised and then had to put it back, now it is stiff to pull when the engine is off in the garage, at least stiffer than before ? Feels ok when on the road, possible odd smell though? But tbh it has been raining and could just be water evaporating off engine parts....
