Re: sprockets-chain

[Ferdinando Di Matteo <aroctech@domain.elided>]

Dear Anthony, I think I know exactly what is wrong.  The wedge is not 
in its proper position so the bolt is contacting he spring only which 
lets the chain go slack in seconds.
Here is what to do.   Remove the ignition key just to make sure the 
engine is not accidentally started.  Pull the adjuster bolt out.  with 
a mirror and light look inside to see if he wedge is in place or just 
the spring showing.   Also look at he bolt end to see if the tit is 
still there.  Let me know what you find and we'll go on from there. You 
may as well pull the cam cover off because you will  have to get in 
there when I give you the cure.   Fred
