The timing marks are off by arround 30-40 degrees. The damper may have shifted but I don’t know for sure. The vacuum at idle is about 7 inches.

(1) Find exact TDC w the ten dollar tool. (2) pull pass valve cover/all plugs & hand turn front crank bolt w 1&1/4" socket/short extension/breaker bar until both of #6 cyls' valves are open and moving and are open the exact same distance & at that point (rockover) the timing marks on the dampener should be within several degrees of each other (could be a slight bit more if sloppy chain). Not a cam guy so not sure how wild those specs are. What carb? Always idled bad? #1 get the timing right & yes may very well be a vac leak. What timing are you showing? After typing this I'm thinking setting the timing right may very well take care of it. Post any news!
