Bill, we buried it a few times, if there was anything besides that glove-knob, I'd have seen it. Sometimes I'd steer, place logs or get my head used for traction under the wheels! That's why I was surprised to see the lever on some q-tracs of AROUND that vintage. Usually well over on the passenger side. Maybe if we had something besides just the "Emergency Knob" we'd have done better off-road.


I've also learned that sometimes... when people don't agree with you .... its best to hold them down and kidney punch them till they agree with you

I knew that vacuum switch was used for something in the Quadratrac TC.

Do all three ports on that switch require a vacuum source?

No, just one source and then the switch moves the vacuum source from one port to the other.

No, just one, the other 2 lines go to the actuator.

There was but only after an attempted derailment. It isn't needed.

I'm also thinking I'm of the opinion (that should be enough distance to make Jay Carney proud ) that, being the manifold supply to the valve in the glove box doesn't actually flow, you might be able to tee into it and use that for your vacuum advance, seeing as I don't believe you have another, independent source of manifold vacuum. Might be worth a try.

I do have 3 vacuum lines into the glove box for the QT.
Now Hi/ Low lever, as I have the TH400 as well.
So that answers THAT question.

I will reread that thread more closely, now that I have some time to give it proper attention.

Also, are you saying the vac advance is hooked up incorrectly?

Again, thank you all again for being patient with my ignorance on this subject.

I may have missed mention of it earlier but I was able to remove my ping by adjusting how quick the vacuum advance comes in. You use an allen wrench in the vacuum pot of the distributor. I do not remember off hand but one way makes it come in faster the other way slower. Mine seems to like manifold vacuum much better than ported as well.

Put the allen wrench in the port and turn it counter clockwise until it stops. Drive, stop, adjust. Start screwing the stop in until you get some pinging, then back it out one revolution.

Beat it to fit, paint it to match!

Wheel, Wrench, Repeat.

The OP said his engine is pinging under load.

Adjusting the vac canister is a wild goose chase, if that's the case.

This troubleshooting through the internet crap is for idiots. I'm done. Have fun everyone. I'm getting a fricken life.

Give a half decent mechanic 5 minutes with this rig and it's done. Problem solved, instead of all this useless chatter.

I think he tried that route already.

Hard to find a half decent mechanic that can work on these old machines anymore vs people who keep them running day after day.

Who pi$$ed in Tip's Wheaties this morning?

Most mechanics are clueless these days, if they can't plug your rig it into a diagnostic machine.
