Should I be concerned that when doing a hill start, pretty much everytime I get really strong burning smell in the car... ? Otherwise the clutch handles fine, no problems with bite, and no slipping, even when the extra 50 bhp kicks in at 6500 RPM. Should I just ignore it until I ge the car serviced next year, or do I need to get it looked at now ?

Car is a 53 Reg Toyota Celica 1.8 T-Sport
