I have a predator 212 with a modified jet, autolite spark plug AR3910X, and air filter I am wondering what is the correct firing pattern? I have the tachometer at 1p2r equivalent to 4 stroke 1 cylinder. The RPM is at 4500 on idle. I am wondering if it is correct as I feel it is dangerous if it is this high. Does it take time for the new engine to settle? I think my tachometer I just didnt set it right.
