Soo..
Extremely encouraged by this..
I grabbed the pile of oem parts to include new plugs wires and air cleaner and went about the businesd of getting it running to lash the valves again and tune the carb.
I have said it before and we all know this...but the difference between oem and even top tier aftermarket on some of these parts is stunning.. I was amazed again at the quality difference between the oem wires and the TWO other non oem wire sets I have used during this process..they are perfect length come with loom brackets that when installed yield a perfect rams horn of groomed wires.
And they all "click" in perfect on both cap and plug side...
Ok anyway...
Put all that in....fired it up and could feel and hear an immediate difference.
Got it warm..rotated 1 tdc compression lashed 123579 then 360 for 4 6 8 10 11 12..got this memorized can do it in my sleep now...apparently some times more accurately than others...lol
Anyway it sounded real good and I will spare you the video of it running with the cup of water with ZERO ripples....i took that video because the contrast was so apparent..before at idle it was so rough it shook tools..heavy ones..off the fenders..the difference was amazing...
So I lean drop tuned for awhile then hooked up vacuum to see if I could tune to max vacuum for an emissions test this week feeling pretty good about it at this stage. ...
First shot no further work showed 17.5 unches if vacuum rock solid no quiver!!!! That was stark stark delta from before as far as zero movement of the needle and also a full 2.5 inches higher than before running at an 850 idle. 17.5 at 5300 feet is real good from what I have read.
This was at 650 rpm and 7 degrees timing (again for e-test)...sorry my phone was upside down...
You may know how exciting watching a vacuum gauge is to me at this point...but if you don't. .let me tell you..I dont miss broncos games...I missed the broncos today doing this work and was very happy about it...this was extreme best case..I was putting this off fearing I screwed up on the piston rings..hoping it was "just" a bum valve job by gunn..and instead it was just too tight of adjustment...
And because she was so cooperative with me today .. I was no longer mad at her..so I loaded the family up and took her out for a dinner date....
