48 Chrysler timing, V/S gas octane

[R Walling]

 My timing is set at 2 degrees ATDC. 

 I thought this was unusual and when asking member Jeff, he sent me a spec. sheet that states after setting it at 2 degrees, it may be advanced or retarded according to the gas octane.

" It should have slight pinging when full throttle at about 10 MPH."

 

 Thanks Jeff. and C49er For the reply's.

Nuisance pinging can be avoided by limiting the number of times you go to full open throttle at about 10 MPH. There may have been a later service bulletin stating that.
