I'll repair and replace all the pipes when i go headers down the road.

Smart move.

@w3wilkes @KenFirch heres that euro tube installed.  Came out super sweet.  And Wilkes you asked if it was a ztherapy and I think it might be now that I have an up close look.  It has their polished look to it in my opinion.  I'm cleaning and readying the carbs for the last step, hopefully attempt to start it this weekend.  I'm going to atytempt to time it, balance, and adjust the mixture so fingers crossed its my first time lol.

Damn that looks nice, really cleans up the look!

Just a thought on ZTherpy vs stock. If it's stock it would have a model # in the casting like the block, head, intake manifold etc.

 if you flip it over you do see an E46 stamped on the tube so it's weird somebody polished this thing it's certainly not that stock look at least what I had before this has that semi glossy polished appearance to it.

Here's a picture of an E46 balance tube.

I believe the non-smog is the E41.

So yes, I believe you have the ZTherapy modded tube, but who cares, it looks great!

So I just went out and rechecked and sure enough it is stamped Japan E46 but what's weird is it's not where it normally would be it's closer to the firewall manifold then the radiator manifold and I would think if this was a normal 46 even though they ground down the spots where the smog accessories were screwed in there's only the single plug on the horizontal location for the booster not a second plug on top next to where I have my booster connected. You would think even if that was ground down he would at least have to put a plug in there there's no such plug so I have no idea what this thing is

Since the E46 is raised lettering it was cast into the tube. This one is slightly different than the one pictured in the ZTherapy master catalog, but I guess they could change things if they want. I know the ZTherapy picture hasn't changed since at least 2017 when I did my ZTherapy carbs.

I was lookong on ztherapy's website. They offer a euro style balance tube. Smoothed and polished. All extraneous holes welded up.

On another note, I didn't know Bruce Palmer had passed away! He was always so nice on the phone... 😞

Well, everything is back and Ive attempted to balance the carbs.  I think i did it right from all the reading Ive done.  i madse sure to balance the airflow in each carb, then tested the mixture by slightly lifting the piston in each.  Idle was pretty much un changed after I got them where It felty ok.  i didnt have an impedence trype rpm reader was relying on the gauge and the sound of the engine.  It feels around 850 from what i can tell.  I'll have a friend come by and double check my work lol.  One thing i did was go back and find the "before" pic and compare it to my new after.  I'm pretty proud of theprogress Ive made as a newbie and 1st time owner.  My work is probably not perfect but I continue to advance it little by little.  Before, first pic from buying it

after with all the changes / eliminations

I really want to thank everyone for all the help these past two years.  I couldn't have gotten this far without the community.  Next up is getting the seats redone and back in so i can test drive it.
