In addition to what everyone else said I recently found my primary plates were catching at idle. Causing my idle to hang up while the rumble of the engine would shake it back down. I loosened the screws just enough (careful not to let one fall) so the plates could move and find a new happy place on the pivot shaft. Sure made a difference when slowly easing into the gas for 1st gear starts. It could be a little twitchy before.

Before I discovered this I thought my pedal or cable was binding but could not find any faults. I did spray some WD on the advance weights in the dist. too.

Good luck.
