Speaking of retarded timing:
Ever since I got my Lago car--over 4 yrs ago--I've felt it had distinctly
less low-end power compared to the '91 200q it replaced. Later, when we
acquired #3 (Tornado Red) that car also had better low-end performance than
ol' Lago. So when it comes time to replace the TB (sometime this Spring) my
expectation is that I'll probably find the cam sprocket has been "off" by
one tooth all this time. This also might help explain the car's somewhat
better-than-expected highway fuel economy.
