The popping on decel is normal if you have a nice crisp lean idle mixture. Because your decelerating and your off the gas, its running on the idle circuit so there isn't enough fuel at the given speed and load, so you'll get the lean popping/burbling. (sounds awesome with headers)

Shawn could probably explain it better.

I6CJ7,

Thanks, I figured this out after I posted that. Should have followed up on that post too...Anyways, it started to happen more when I turned my screws in to 1.25 turns out from 2.0, and as you said when you lay off the gas your running on the lean mixture of the idle circuit.

Thanks for chiming in with that.

SC

Yup no problem! At idle you should have a lean miss or stumble about every 7-8 seconds i believe, when its perfect.
And that lean popping will increase like you said as your lean out the screws more.

I love the sound of my headers, i need to get a sound clip of them.

Touchdown with the two point conversion!

Touchdown obviously is that I passed smog.

Two point conv is that I went to a smog guy that knows his stuff about carbed wheeling rigs. He asked me how I tuned it and before he even put the probes in the exhaust, he turned my idles 1/3 turn in, and then he probed it and it passed smog! He said the vac tuning makes it too "fat" (see! He knows his terminology).

After the test he ran it on diagnose so he could see my numbers in real time, and he said I'm a jet lean on my mains. Good to know.

Then we BS'd about carbs for a sec. He asked me how I like the Holley off camber to which I replied about its painful weaknesses. You'll like this one Matt, he then recommended a Qjet and told me some shocking stories about what he's seen Qjets do offroad.

As if I wasn't sold before, I'm really sold on a qjet now!

To me, your plugs appear to have the correct heat range, your mixture looks good, and you could use slightly more timing.

Do you really think fuel was flowing thru the vent, causing flooding, on an incline? I'll be interested to see if your extension fixes that problem.

Hey guys, it's been a while for this thread, but...

Matt,

there wasn't an issue with fuel coming out of my float bowl vent after all. Remember that crazy fuel tube contraption thing I made? I'll repost the pic soon. My lean back stumble is something else. Probably a lack of a Qjet
