my timing is jumpy and i can't get a definitive number because the white mark on the crank pulley doesn't line up with the pointer on the timing belt cover. it would line up to the pointer for a quick moment and fluctuate back and forth.

i'm running JG turbo camshafts on my LS engine, would this be a factor with this timing issue?

i'm using the Craftsman advanced timing gun with the dial.

 

when you shoot the timing light at the crank pully you are supposed to look for the red mark that has the 2 marks above and below it.. i have never seen the white mark appear with a timing light only the red one..

make sure you jump your ECU.
it will smooth it out

 

also the reason u see the white mark is because your shooting 16 degrees of advance

nextelbuddy isnt using an advance gun, thus thats why u are at the red.

 

my bad lol i didnt see the last part of his post... i learn something new every day.


i didnt jump my ecu when i set my timing on the dizzy when i used a timinglight.. would reseting the ECU take care of me not jumping it at the time?

yes, the ECU was jumped prior to checking the timing.

thanks for the suggestion though.
