what causes timing to keep advancing? i cant seem to get my timing to stop advancing at all. at 4500rpm its about 50* and climbing. stock hei dist with msd ignition. any ideas?

 

What is making you think it's advancing?

How does it run when it's "advanced", compared to when it's not where it belongs?

 

when i time it at 3000rpm im at 36 degrees. i then rev it up to see if it quits but as soon as i hit 4500 it starts to climb from my original setting all way up to 50 degrees. i dont have vac advance hooked up. mech only

 

What springs do you have in it?

Did it come with a manual?

Many HEI distributors continue to advance well past 3K with the stock springs. Just because you set it at some random point at 3k RPM does not mean it magically knows when to stop.

You need the timing adjustment kit for a HEI distributor.

Second thought is your timing light compatible with the MSD ignition? Many dial lights get screwed up be the multi spark. Your best best is timing tape and a normal light.

 

IT had the stock springs which were really stiff, i changed them out to the gold springs that i purchased from summit. i have a normal light plus timing tape. how would the spring change opening rate? im a little "confused" by it

 

light weight springs makes the timing all in sooner.whereas stiffer ones make it come in at a higher RPM
