"Any suggestions as to gauge location? "

in a pod to the left of the inst cluster on that little shelf.

My 1600 has the hazard switch there, else that's probably where I'd put it.

I'm not sure I want the 3-gauge pod to the right of the cluster either.

I have an idea on how to create a neat little bracket and mount it to the right of the center console, in the corner where the dash meets the console.

Let's see if I can pull it off.

Meanwhile, today in the warehouse:






I utilized a few zipties to get the gauge where I want it. I'll start making a decent enclosure that mounts where the gauge currently is. Maybe next week.








The car is definitely running lean, but I hope to take care of that next week. Some time during the engine bay work, I must have wiggled the blue alternator wire loose. I ran the car for a little while, but promptly killed the battery. I scratched my head for a while trying to figure out what it was. So I left and grabbed some food (a burrito), and when I came back, the first thing I checked turned out to be the issue. Burritos really do work.






So I hooked up a trickle charger to the batter under the rear seat.
Side note: My rear seat's horse hair is disintegrating. I need to do something about this.








And this charger is pretty cool. It showed me that when I began the charge, the battery was 11% charged. It knew the battery was an AGM battery, which I was also amazed by. In the photo, the battery was up to 39% charged.









I also swapped the rear bumper back to the one without the three main holes in the center section. But I forgot to snap a photo of this.



That's all I have. I think I'm going to get off the internet now.

9.9 is rich as hell, not lean. What's in those burritos you are eating?


Idle is the easiest adjust to the AFR on with a carb. Screw the idle mixture screw in (clockwise) until you hit mid-upper 13s.

Dang it. I meant rich but I wrote lean.

But I meant rich. And I'll do what you suggested.

14.7 would be best for idle as well as cruising with no load.

"Best" for a carbureted vehicle? You sure about that?

With no load cruising/idle yes. I know it's usually richer for carb'd vehicles to avoid lean mixtures in a cylinder. Aiming for 13 to 14 AFR instead won't hurt and safer I suppose.

From reading various 38/38 carb tuning threads, 14.5-7 at cruise sounds about right.

WOT should be about 13.1, and Idle should be over 12.5 is what I'm seeing online regarding the 38/38, or just in general.

I've been doing some reading up based on this thread here:

A little ahead of schedule, but I pulled an extra set of strut housings out of storage and am preparing them for coilovers. Give me a week and I'll make your wildest dreams come true. And an extra front subframe. I'm going to do something with that one too.








I played with the air/fuel screw on the carb today and got it to idle a bit leaner. I was at 13.1, but I backed off and left it at 12.4-12.6.

And this is my view of the gauge when driving. Not the best, but not the worst. I can think of 20 other places to mount this gauge that would be significantly worse than where it is now.

Love this thread.

Carb's are a mystery to me. I've only dealt with snowmobiles. I'll stick with my laptop tuning lol.

I feel the exact same way. I don't like em, but I respect them.





But anyways, sneak peek:







and reinforced housings because I plan on taking it off some sweet jumps

[RCM3]

Nice choice with the suspension upgrade. So are those your GC housings^^ yours or just pics of what the final product will look like? Wondering since you mentioned a couple days back youre preparing housing for the coil overs. What I am getting at is that I'm curious about your choice on the front sway bar mount location and if you gave any thought about the length of the threaded piece that the adjustable collar moves up and down on.
