How about the AER72S plug?
Is the 2407 plug the same as AER72S plug?
I found this on a different discussion board. Can ANYONE tell me if its accurate?
Warning, The Ols Champion Number AER-72S was the spark plug for the M-715 OH Cam Tornado Engine, only. It is 1/2 " Reach, the 2245 is 3/8" Reach and is the latest Autolite version for the M-151.
