That is hard to do for most of us. That's why I said to have it rich enough that you are certain it is not the rev limiter.

If you hold your tach on the saw and rev the saw up and it goes into rev limiting, the tach will go nuts.
We should share what we know... someone may learn...
That knowledge can live after us... and that "Pays It Forward".
Be all that you can be . . .

I was having a hard time telling the difference between 4 stroking and hitting the rev limiter.

If your using a tach. Here is what you will see, bouncing around rpm all over the place 11k 12k 13k  up down etc = hitting rev limiter

Fat 4 stroking  showing nice steady say 12K = 4 stroking.
