Here's food for thought. I noticed on my 180 that when I pull away from a stand still, the exhaust is a lot louder until I fully release the clutch. Now when I stationary the other day, I kept pushing in the clutch then letting it out and it did rev a little bit (or at least the revs went higher only by a fraction though).
Is this a little bit of Abarth trickery to make it sound better / provoke it to back fire? As I have noticed when the car was cold, going from 2nd to 3rd at low rpm, when I lifted the clutch it did make a little pop
Well, at least I thought it did haha
I do miss my 160 back fires lol
