Normally I can find the answer for just about anything car related on the internet but I can't seem to get any positive direction for this vacuum reading..
you can see it at https://vimeo.com/244265209

It's a stock v6, running points, everything is new. No leaks anywhere on manifold. It runs great sometimes, but always starts spitting at some point. No consistency.

Cheers!

"worn valve guides"

If they are new... how would they be worn already?

Thanks for the responses.

I've adjusted the valves by the book a few times. But I'm not certain about them.
I hear clacking when it's cold, and it seems to run better...after heating up, the clacking is less and it runs like crap.

The vacuum gauge will stabilize a little bit after revving it up to higher RPM.
I may have to try to adjust the valves while they're running which is really hard to do...

Bonkers. If you do though get someone to video it and post it up, it’d be great to watch.

A very good technique for destroying a perfectly good set of feelers.

The factory service manual actually says to do that, although no one does... I've come to realize that the distributor is a garbage aftermarket one that I'm going to replace with OEM. It has stopped making sparks consistently now.

Thanks for the inputs...there seems to be more knowledge here than in some of the land cruiser enthusiast forums...
