I have tried restricting intake flow multiple times but each time the clean smoke starts to go gray and starts to smell wrong..
Tried several brands of hardwood lump and I might as well put the brisket in the oven, the heat produced is at the expense of the flavor that I lose by not burning wood and making wood coals.

While thin blue smoke to just a heat signature is a perfect scenario it does not make or break a cook session. When applying new sticks it is common to see some white smoke for a few minutes then it should clear up again it is all about fire management and learning the cooker.

Good luck with your project. :)
Always remember slow and steady wins the race.

Of course, fresh sticks always burn dirty, and that's why I preheat even these tiny sticks and also leave the firebox lid open until the new wood to comes to full flame before closing the lid.
I really am in control of the fire and cook chamber temps, my issue is that sometimes using tiny sticks the coal bed gets too small to get the next stick going quickly.
Another factor is that I have half a cord of oak I don't like and need to dispose of, so a burn barrel will kill two birds so to speak.
I would have a source of fresh coals as needed and sooner or later I can buy some more good post oak..when I have the room to store it in the wood shed.

.....looks like an Old Country , if you'll measure your exhaust pipe it should be about 5 inches , now measure the opening in the cook chamber to the exhaust pipe it's only 4” , that smaller opening is restricting the air flow , a 4 inch pipe for that size smoker is small , you may have to clean it up with a hack saw blade or pneumatic saw , take advantage of the 5 inch established pipe , if you decide to make this modification after burn again , see how the pit reacts to better air flow and adjust from there.......it's a process.....straighten out the front end then go to the firebox

…..if not you might try moving the fire / coals forward or backward in the box to see which way provides the best control

…..rely on the draw to pull heat from the firebox into and thru the cook chamber weather the fire is close to or far from the opening , most important is the draw , if you have a 5 inch pipe use it , fire back cooler , closer , hotter

I read Franklin's book and watched all his videos about a dozen times before my first brisket cook and have played with fire location,including height from the floor of the firebox which he does not talk about, all in an effort to lower cook chamber temps.
Also have tune plates and have raised the cook surface an inch to get away from the overheating tune plates..
Your suggestion on the outlet diameter is a new one and as soon as the fence guys get done in my back yard I'll pull the cover off my cooker and get some measurements..
I've brought this up before but anyone know why or seen others who, like Franklin, don't run a grate under the fire, just have the wood arranged on the floor of the firebox, sitting in the coals and ashes?

I was thinking 55gal drum or something cheapo..but hey, I'll suggest the cap off a tank and see what he says, who knows he may have one already.

You can get tank heads new, too; I put together some friends that all wanted some, then ended up with 3' x 5/16 tank heads for aroun $110 -120 each as I remember, delivered. just tell them it's for BBQ pits right away and they can sell them without the certs for a LOT cheaper. The guy told me they come out of the same pile, they just don't have to spend the money to back up the ASME certs.

He found a 30 gal race fuel can, I told him I wanted a smaller one so when I get it, I'll post up pics..and yes I warned him about cutting/welding on a fuel can.

That was some good advice! My 5 inch exhaust pipe was connected to a 4 inch outlet opening..
I borrowed a sawzall and started slicing, ended up making a series of straight cuts resulting is sort of sunflower pattern in the metal and pounded/folded them back toward the outside.
The pipe was offset to one side so that on the left there was only about 3/16 inch ledge with the opposite side at around an inch..top and bottom were pretty centered at around 1/2 inch each.
Can't wait to try it out.
Thanks!

I have the same pit as you. I made my exhaust longer and it seemed to help with conto ling the heat a lot. For the test run I simply wrapped it with a long piece of cardboard and taped it on.
