Re: spark timing question

With a modified engine (assuming yours is) you have to find out what ign 
advance suits the engine (usually on the rolling road) and then make a note 
of it for future reference.  If the cam is non standard then the distributor 
ought to be as well.  Have a read through the ign chapter in Vizard's book.  
If the cam is non -standard the idle will be higher than standard by virtue 
of the change in overlap.
