Thread: Qjet vacs #2 - Denny or Techinspector?

Thanks guys for the info, I understand now. If I have any breather spitting, I will switch the PVC to that port 6.

I started up the engine with this new carb and WOW what a nice difference. It ran great for 10 mins. I set the cold and hot idle and let it run in. I got no stumbling when pushing pedal quickly to the floor. Couldn't drive it right now due to snow here. Few more questions:

- On the port above the fuel inlet where dist was hooked to gives full vac at idle. If I want ported vac for dist, I need to choose another port, correct? Ported is no or little vac at idle and increasing with more load/rpm if I've got it right.

- I think my vac advance on the dist is not working. I disconnected the dist, plugged the port, and the timing was 8-10 degrees. I plugged it back in and the timing was the same. Remember that this port was pulling max vac at idle. I have lightest springs on my dist if that matters. hmmmm

- With the vaccum gauge hooked up, I turned each of the idle mixture screws in until stumble and then back out enough for smooth idle (about 2.5 turns). But the vac gauge hardly changed when I did this. I understood that I should dial in idle mixture using vacuum gauge? Maybe I should not use the port above the fuel inlet?

- I'm still running quite rich based on the super rich exhaust when I goose it. The gas has stabilizer in it, but is still 6 months old, plus the engine has been running on and off for carb tune all winter. I'm guessing I should run it as is, drive it around for 10-20 minutes, fill with fresh gas, and then see if it running rich after that. If I still get rich then, I'm thinking I have to reduce the jet size.
