Always rev the motor and watch the timing during RPM climbing.
The valve train has to be loaded to properly set the timing.
It can't be done right at idle, or at a constant RPM because there will always be slack in the chain.
As was said prior, make sure the cam isn't walking either.

maybe if you knew how to set an advance curve ya wouldnt need to gut the distributor, slack in the chain? when the engines running it should take out the slack or maybe if your a real racer you would use a gear drive hotshot... :lol:

I do use a Donovan gear drive, and MSD pro mags dont have springs/weights timing curves, so I didnt gut anything.
Any other comments to put your foot in your face?

The springs/weights determine the timing curve of the distributor.
Most distributors can also be changed as to the total amount of timing advance.
So, to find that out, you'll need to find someone with a distributor machine to spin it up and find out how much total advance, what RPM the advance starts, and how fast the advance ramps in.

your ride idles at 1500 rpm,what effect would it have?your gonna be faster? the effect would be your totally advanced,mechanical,and centrifugal,meaning around 65% more spark advance,meaning the engine will respond,yes,one more time to put my foot in my mouth,why would ya need a distributor machine.I just told ya how to check the distributors advance curve the easy way, it isnt rocket science....
