variocam and solenoid

[barks]

thanks for reply dude,

i have access to snap on solus pro but using my tablet i can see the advance fluctuating at idle which dosent look right to me,

i think its a tensioner.

the clattering noise when warm at idle and decelerating below 3k rpm coupled with the advance fluctuation points that way.

is there a test for a tensioner without pulling cover off?
maybe a small bolt i can undo and test the tension?

cheers
