when you correct the balancer for true TDC using a piston stop you can also mark the balance at 36deg BTDC
that is exactly 1/10th the way around the balancer from TDC.
what distributor? MSD read the instructins it easy.
GM HEI is easy too. but differnt
some advance timing lights get all wacked by a MSD spark box.
marking the balancer at 36deg allows you to verify the advance light is accurate.
if its a old stock balancer a slipped outer ring is suspect. if thats the case replace it as a slipped outer ring is soon going to come
unglued and it ain't pretty.
Aftermarket timing tabs are always out f wack. There are three different balancers/timing tab locations for TDC.
and six different way you can mismatch that.
You cannot set the timing or tune untill the TDC pointer is accurate.
A 750 carb always makes more ower than a 600. but any all carbs will need spcific setup. Once set up the 600 will run fine.
