I just got done doing the belt on my SR, I do not care for the AC but I am getting efficient at it. Not being able to get the impact on the crank bolt had me worried but then I settled into making a spanner and the job went fine.
The timing blade on mine was giving to much advance. Enough to be out of the knock sensors range.

Cheers, Charlie
