The Plus to me is SC's trump card, it is a perfect size providing excellent flavor and vapor production.

Couldn't Agree more! On the + :thumbs: IMO it's a nice balance between to big & not enough Capacity :)
I dial down the AFC to the smaller Slit on the +, So more air isn't a selling point for me. I kind of figured the Titan was a novelty item, but was still curious on it's performance.

BTW the "predator" Was a great carb back in the Day, For a 4 wheeling rig :)

It's a bit spendy, but dna and fits the Titan perfectly with no overhang. :D

Is it better than the Plus? No it's a novelty juice burner with airflow for days.
It's like pulling air through an old 900CFM race carb.

Major neck beard cred when you stop into the local Clouds Bro Clouds B&M for a show and tell. :vapor: :lol: I picked one up #BecauseSteamCrave. Steam Crave is coming out with a PWM mod for the Titan and probably the new 30mm Dripper. I'm not interested in their mod, I'd build my own but it should be sweet! :thumbs:

You can dial down the airflow to the single holes on the ring, the smallest one whistles, the oval isn't too bad depending on your build, which needs to be huge. I have a pair of 7 wrap 4mm AVS framed staples in mine (they look tiny on the 30mm deck) at 125W and it is a very cloudy/tasty beast!

The Plus to me is SC's trump card, it is a perfect size providing excellent flavor and vapor production. I get tired of constantly filling 4ml tanks, that I rarely use them any more. It would be nice to go back to the days of the Rose V2, I still use one of mine as a stealth MTL rig.

Now what would the wife say if she saw a carb sitting on her chair? :laugh: Like I'm not guilty of ever having car parts on the kitchen table. ;)

Might be on to something for a new no wick atty, just a hot wire. Use the venturi effect to pull juice past the coil, you know, with interchangeable jets, or drill your own. :) Add an electric accelerator pump for that "mash that pedal to the floor" boost, maybe we can get Evolv design a board control the pump, adjustable flow for the boost. :thumbs:

Heck we could even go with electronic m/c secondary jets like the old computer controlled rottenchester 4 barrel's, for that even mixture in the middle of the hit. :D

Remember having to set the dwell on those? Oh yeah, and don't forget to swap out to the "purple" power piston spring. :laugh:

The Predator is not my picture, just something I stole from the interwebs. I didn't tinker to much with carbs back in the day. I tried installing a new intake manifold and rebuilding an old quadrajet for the Berlinetta one weekend when I was young and thought I knew everything... :facepalm: Finally ended up reinstalling the 2bbl setup so I could go to work that Monday.

I never bothered with them again... ;)

If I couldnt fix it with a can of carb-cleaner, I didnt touch it. A man has got to know his limitations! And those things were damn sure one of "my" limitations.

What, you don't like figuring out where the forty-leven jillion parts scattered across your workbench go back in? Carb rebuilds are typically not very complicated. Setting them up for peak performance is where the brains have to kick in. Some carbs were never designed to stay in calibration either, the early Rochester Spread Bore QuaudraJet being a prime example. I could have single handedly built 6 3000sqft homes with the hours I spent with those dern things.

I don't think any body ever had a good experience rebuilding a Carb!
I had a buddy get so frustrated, He put His Rochester in a Vise & Squished it!
Back in the Day I would just replace them, Holleys were cheap!
Now a days every time I turn the Key I thank God for Fuel Injection :)

Back when I used to race I never could get a quadraflop to work. I had a buddy bet me he could set up a quadraflop on my car that would perform as well as my Holley 780 did. He threw an adapter and a quadraflop on my engine on test and tune night within 3 passes he had it dialed in. On the 4th I went 1/10 quicker than it did earlier with the Holley. "It's all in the metering rods" he told me.

Want to have some real hair pulling? Tune Weber IDF's. Took a bucket of emulsion tubes, idle jets, main jets, and air bleed jets since they all interact with each other. But with an individual barrel per cylinder once tuned neither a Holley or a Quadrajet could hold a candle to how smooth they transition throughout the power band.

In truth Rochester carbs got a bad rap they didn't deserve, I think a lot of it came from the early days of GM rushing and trying to comply with new emission standards that caused driveability problems that started to show within the first one or two years of the cars age. All of us back then were trying to grasp how the entirety of all the new emission components tied together, everything had to work in sync and we had little training available to us from GM in those early years. It was easy to blame hesitation and lag on the carburetor, that's what we were use to seeing as the cause of most of these problems before those new emission days but now we had engines set to run lean with new parts and settings added that we had never seen before, a computer (what the heck is that thing!!??) new sensors, EGR valves, new parts added to the carbs, ......ed timing and cat converters that would plug and restrict. A LOT of carburetors where rebuilt only to end up still having the same problem so we scratched our heads and blamed the carbs, JUNK!!

That "purple" power piston spring I refereed to earlier, those springs were color coded, you'd get the number off the side of the carb throttle plate and look up what color spring was to be installed during a rebuild. The purple spring was one of the stronger springs and it was common to throw one in an attempt to eliminate a lite acceleration lag, you crossed your fingers it was a quick fix. For a few years early into those new computer controlled carbs the parts dept sold a TON of those purple springs LoL. A lot of times it was the EGR valve opening too soon that caused that lag, it was common to see guys whack the top of the EGR valve with a rubber mallet bending the sheet metal cover to put more pressure on the EGR spring to try slow the opening of the valve. Even GM was trying to solve problems with jerry rigging, they put out a bulletin with a list of vacuum delay valves to try putting in the vacuum line that went to the EGR valve, better then beating the valve I guess LoL.

About five years after those new GM emission systems came out I left the GM dealer and went to work in a VW, Audi & Porsche dealer where all the new German vehicles were fuel injected, Thank God! It didn't break my heart to leave GM behind.

In the early 80s, in the years before we got married, my wife had a 1977 Firebird that her dad gave her as a hand-me-down graduation present. 305 cubic inches of non-stop ping. Highest octane Sunoco gas, flat road, steady 60mph, and the damn thing sounded still like marbles in a tin can. Dealer said "that's normal". Nobody I asked to look at it ever found a way to fix it.

At the same time, I had a 77 Rabbit. With CIS injection it ran so clean it was certified without a catalyst and ran perfectly on the cheapest leaded regular. Wanna tweak the mixture? One screw in the fuel distributor, easily accessible with a T-handle 3mm Allen wrench.

Fuel injection FTW.

Or young guys like me porting double bump heads with 1.94 (2.02's put the seats touching so for street I never used those) and 1.6 valves drill and pin the studs and double springs with the spring seats dropped .100, freshening up an 0010 block, drop a duntof whitesheet cam in, a dual points corvette dist with a switch to select the advanced set when in high gear, a strip dominator with a Holley on top, and ...... headers. Get about 475 hp out of that combo and with an M22 rock crusher get low 11's in a Camaro or Nova and still be streetable. Use a 5.5 power valve in that combo or else you will dump too much fuel at idle due to low idle vac. 78 or 79 mains IIRC and the larger accel pump well and diaphragm. My Father and Uncles taught me how to embarrass the guys with the high dollar cars with low budget (in our means) tech.

Nowadays that performance can be had from the dealer but low 11's in the 70's and 80's in a daily driver was rare.

Happy berfday tibs

Hey I was gonna ask you guys, is there any way to fix an old washing machine that seems to be leaking from the undercarriage? I checked all the fittings & they're totally dry, (btw, this washer & dryer are the only 2 original appliances left, so they must be about 18 years old) or is it time to get a new one? Wasn't really planning on that rn though, we just got a new fridge. [emoji19]
