Adjuster it loose cause valve is not fully closing, and is not keeping
pressure on the rocker...
gonna try one more time pouring cleaner
down sparkplug hole but doubt thats it...
found a pair of heads with
35K for $500 but prob worth few more for rebuilts?
Been googling
this and found a intresting post I want to share showing head removal w/o
pulling timing
chains.

Thanks
