It is best to tune a 4 stroke with a tachometer;

It is never a good idea to tune an engine with a tach.

I thought that you tuned with a tach to find the highest rpm and then richened until the rpm backed off a few hundred rpm's. Have I been tuning my Saito 62 wrong? Just curious why you say it is never good to do it that way when it seems to me like just a different way of doing it.

I am not trying to start an argument or anything, just curious as to the reasoning behind your statement of it is never good to tune with a tach.
