Hiya Alvin! I’ve seen these used for vacuum leaks but not for mechanical timing. That’s a cool way of checking visually, rather than a compression, or leak down test. Thanks for the tip, I might look into one of those machines.
Hey Troy...yes, if smoke can get past a valve that's supposed to be closed, then there is a problem. Also it's great for checking the stuff it was designed to do, but you know me I have to push for more! Lol
Throw a pickup coil at it! Had a few over the years acting the same way... turned out to be a bad pickup coil even though the wires were ok. Or seemed to be ok...
You are right! I cut apart the rubber insulator holding the three wires, where it passes through the distributor, the lower wire had pinch mark with a little black dot in the wire covering, it looks like the lower wire has been shorting to the ground strap connector right below it. I added a little bit of a tape barrier, and she runs much better... good enough until the new comes in. 👍
It sure was Chuck! It happened so randomly, making it hard to track down. I had already replaced most of the ignition parts when I bought the engine...so now a pick up coil will complete the tune up. Lol
Hey Alvin, How can you tell if you have ignition timing that is off a bit? the 66 bird runs but runs rough at curb idle, then seems to smooth out once you give it gas. 😄
You can check the timing with a timing light very simple to do, however, it sounds like you have something else happening, an issue with ignition wires/plugs (make sure the plug wires are on the correct cylinders), the idle mixture is off, a vacuum leak, the choke is not fully coming off or the power valve is leaking...it's hard for me to say from my chair, which one(s) are the issue, but these are a few things to look at, start with the easy ones like vacuum leaks, choke and idle mixture.
Hey George, I've known 442Olds for as long as I can remember, and when he suggests a fix, I take it seriously...he has many years of experience, and as always, he was right. 😊
I've not seen the smoke test before. Very interesting. Thanks for the video Alvin
Well worth the money Matt, it works great for leak detection on evap, and vacuum leaks.

@@J_R_Shop Bingo!
Glad you got it, that was a head scratcher for sure ~ Chuck

Hello Alvin. I see you figured it out per comments by @442Olds7. Those were odd symptoms.
