neighbor has a '65 110, Pg,vert in his shop-which, has vacuum readings jumping back & forth from high to low at idle.  He is stumped.  I think he has done all normal tune-up procedures.

Joe!!  What RPM?  in drive?


#1 leaky intake valve.....  or # 2   many engines show this at 500-550 rpm...  if it's smooth  forget it!
