I am now going 65. I have built rods, hot rods and street machines. In these high horse power engines we would ride the clutch...sort of grabbing and no grabbing...this is so you could jump at the start and you would have a little friction built up. Clutches usually would get these problems after time. Maybe the previous owner rode the clutch a little to much. For everyday driving I would down shift but before I stopped then I would pop it in neutral. When the light changed, in gear I went and took off. Just plan old normal driving. Try a few hard starts and see if you can wear down the spots...maybe it will help
