need help with tensioner

[thesus]

hey guys i just replaced the cam chain guide on my 76 and was setting the tension for the chain but when the push rod is flush the adjuster is too far in to put the acorn nut back on, did i forget to do something or is my cam chain streached? my manual does not address this problem. thanks

Under normal conditions, I'd say the chain is stretched and needs to be replaced, most noticable if chain is super-easy to reinstall on cam. Under abnormal conditions, with questionable history, you may have tensioner parts mix-up, wrong tensioner plunger and adjuster...
