Title: Altering ignition timing in Ohv
Post by: fi131 on November 09, 2013, 12:23:28 AM
I have the ignition timing in my 131 ohv set at 10o BTDC (factory setting)
Do you think that giving a few degrees retard or advance might  benefit in an ohv mirafiori performance ?
Or is it not worth changing factory settings.
The only conversion in my 131 ohv is a marelli electronic ignition set-up i have added recently,with the  electronic dizzy giving  max  centrifugal  advance 4-5 deg more  than the std point one
