Good job, it always amazes me how much carbon builds up in an a series engine, I have took other cars apart and nothing compares to the a series for it, I took a k series apart and it was really clean, must be to do with the combustion chamber shape or su carb.
yea always get quite a bit of carbon build up in an a series, this engine has done nearly 85000 miles, but good job it was not running to rich
