Not sure I have to check that out.
Well I think I found the source of some of my issues dammit.. such a idiot..I suppose this brake booster port not being plugged causes lots of issues!! Including massive air leak!! Omfg I feel like a dumb dumb..
well at least you all get to see this rear discharge tube mod

Discharge... Huh huh
Well my todo list just got really long..
So because I had carb issues it was running lean and enough so that it made some heat and melted through the trans modulator hose, the exhaust collector bolts on one side are gone, the other side about to fall off, and I tightened them right before I loaded it on the trailer.
When I had the carb apart I saw the goop in the modulator line and thought wtf is that.. well it was melted rubber that clogged the line!!
I broke a rear shock mount on the axle. Didn’t damage the shock magically!
The battery cable to the starter almost had all the insulation melted off!
I pulled a plug just to see if there was any indication of damage and there wasn’t but I am gonna do a compression check when I change plugs to tune it just to see where it’s at.
Freaking super lucky I didn’t blow it up and the trans.. I suppose the motor being bad running might have saved my trans..

I have lots of those lists!
How does one rip off a shock tab? Were your tabs made out of 18 gauge?
Well now it sounds a lot better, sounds like it wants to idle now instead of sounding lazy, just need to turn the idle down some. The no vacuum leak and better timing gave it more life, although I am a little worried how much sand you pulled in that 3/8" hole. Next time you have to close the butterflies all the way to get it to idle you should check for a vacuum leak sooner, that was your red flag... 
BTW, having no vacuum modulator line won't hurt your trans, the vacuum modulator just lowers pressure with vacuum for softer shifts at part throttle, so if you leave that line off it will just have full pressure all the time. In fact in a performance build if you don't care about firmer shifts down low you can try just leaving the line off and see how you like it. (Just remember to plug the hole)
I like to put all wires and hoses near the headers in that heat shield tubing thats made of an inner layer of high temp weave insulation and an outer layer of heat reflective foil like surface.
I thought you cut off the choke tower? Different carb?

Lights and turn signals??? Nooooo... all you need is this and then they can’t catch you to write a ticket.
Yea I just had a dumbass moment, the oil definitely shows it ingested dirt with how black it was.. so that’ll get changed..Well now it sounds a lot better, sounds like it wants to idle now instead of sounding lazy, just need to turn the idle down some.

I just have been delirious when I was talking about it before. But that tower needs to go..
I didn’t know that about the modulator, glad to hear it, I may try without that and see how it feels.
And I’ll play with the idle and see if it’ll idle lower and in gear. I know my idle feed restrictor is incorrectly sized. And idle air bleeds are incorrect also. I haven’t indexed them yet so I have no idea if they are way off or just a bit off.
Much to do!!
And the shock tabs were my fault because of a cold weld on the axle side, I was rushing and it was windy and just trying to finish it made me just bring the suck.. it just so happens to be the first weld I have had fail.. not proud of that..
Okay so I fixed this crap today.. the broken tab you can see where I made the cut to move them up just a hair. Those welds didn’t break prob because I went over them 2x. But the corner weld was too cold and broke right off I didn’t even know until now you can see a stalagmite looking seal and that means the shielding gas blew out.. I suppose that’s what I get for rushing.
Good detail and repair, and big respect for showing lessons learned. I know I’m always worries about flowing too few amps.
