Stocker carb, removing choke plate ok ?
 

I don't see anything in the rule book on this, but in the accepted products document there's a section called carb notes, and it says it's ok. Although the way the documents reads, it's not super clear what it applies to.

Re: Stocker carb, removing choke plate ok ?
 

The choke plate has to stay, but can be open and inoperative.

Re: Stocker carb, removing choke plate ok ?
 

Carb notes apply to carburetors used in Comp and SS/Modified, not regular Super Stock or Stock.

Re: Stocker carb, removing choke plate ok ?
 

page 62 does mention Stock, SS, etc. But the context is replacement carbs, so probably doesn't include alternate carbs..........

Re: Stocker carb, removing choke plate ok ?
 

Take it off and put it back on if they tell you to.

Re: Stocker carb, removing choke plate ok ?
 

Just be sure you keep the choke plate and shaft in the tool box in your trailer because you will have to put it back on someday.

Re: Stocker carb, removing choke plate ok ?
 

In tear down, if I was a Tech guy and found a car running without the choke plate, my recommendation would be for a 1 year suspension due to an intentional violation of the rules.

Re: Stocker carb, removing choke plate ok ?
 

I doubt if found during a spot check after winning a 3rd round heads-up, that they would allow you to put it back on.
As Bob said,...maybe in a year or so.

Re: Stocker carb, removing choke plate ok ?
 

So I get where the rule book does not allow removing the choke. The reason I started this thread is because it looks to me if you are allowed a "replacement" carb, i.e. edelbrock, or quickfuel, which seems to be legal in stock, it spells out in the carb notes what mods you can do, and that includes removing the choke. That doesn't make sense to me, but that is what I see. Maybe I'm reading it wrong.

Here it is...……

From 2019 NHRA Rulebook Section 11A, page 3

CARBURETOR
Must be correct year, make, and model specified for car’s engine;
fuel or air bleed passages may be resized. Drilling idle holes in
primary
throttle blades permitted. Other modifications prohibited.
Sandblasting, grinding, flash removal, dry film coating, or any
other modification to carburetors prohibited. Replacement
carburetors permitted provided they are same model, type,
throttle bore, and venturi size. Computer carburetors use latest
model non-computer carb for engine application.

It also doesn't say that you can poke a sharp stick in your eye....

Unless it states that it's allowed, it isn't...

PS:
This is also the rule for Super Stock....

Re: Stocker carb, removing choke plate ok ?
 

It's certainly in black and white. i still do not agree with it "stock class" should have a choke plate in the carb. thats how they came stock.....

Re: Stocker carb, removing choke plate ok ?
 

What you are looking at are the "rules" for SS/Truck, FWD SS and Super mod and Comp. Go back and read the WHOLE thing .....SLOWLY.....

Re: Stocker carb, removing choke plate ok ?
 

Other modifications prohibited. Third sentence in stock carburetors in current rule book. For me a 50 cc Reo pump would be great but not allowed, a metering plate change in the end carbs would be great, but not allowed. An inch spacer would be great but not...........

Re: Stocker carb, removing choke plate ok ?
 

I have learned something today. There are some threads that should have never been started.
I agree the rule book is clear that you can't remove the choke plate in stock. I was merely trying to understand the carb section in the accepted products document

The way I read it, the carb notes that start on page 62, that for stock, SS, SSGT, SSGT truck various mods are listed, including removing the choke plate.
Looking at the rule book for SS and Comp, I don't see anything on carbs at all except they do refer you back to lower classes.


In any event my carb will have the choke plate intact, and if any of the nhra tech auxiliary would like to come by at a divisional, please do.

Re: Stocker carb, removing choke plate ok ?
 

From the 2019 NHRA Rulebook....

Another key to understanding the NHRA Rulebook is
that certain classes “build” from another.

When the Rulebook states “Requirements and Specifications for
… are the same as those for ...” you must read the referenced
section first.

If after reading the Rulebook you still have questions, consult
page xiv for hours and phone numbers where tech personnel
may be reached. These phone lines are extremely busy, so
prepare your questions in advance.

Remember, it is your responsibility to follow the standards in this Rulebook that pertain to your vehicle

AND

SECTION 12
SUPER STOCK

Requirements and specifications for all
Super Stock categories are the same
as those for Stock Cars - Section 10A -
with the following exceptions:

PS:

You got some bad and incorrect info from some of the people who responded to your post. It is your responsibility to make your racecar legal.

My suggestion would be for you to read the rulebook completely starting at page 1 to help you better understand the process.

Re: Stocker carb, removing choke plate ok ?
 

And IMHO, the rulebook is intentionally vague and confusing...

Re: Stocker carb, removing choke plate ok ?
 

I get it Billy and I don't disagree ...…

I think that between the 2 of us we have been doing this for over a hundred years....

You have to learn for to walk before you learn how to run....

Starting out getting tossed is not a good thing...

My big problem is people advising him that don't have the background..

Taking a conservative approach to the rulebook might not be a bad thing until you find out what's going on...

It's better to know what is legal and what's not..

Take care..

Re: Stocker carb, removing choke plate ok ?
 

I think we spoke before about your combo. A while back. There are plenty of guys that build legal carbs that would make it a bit easier. Pm me & maybe I can point you in the right direction.

Re: Stocker carb, removing choke plate ok ?
 

As a builder of Drag Race Thermoquads for over 40 years I can tell you the rule that you must have a choke plate in Stock and Super Stock has never changed! I wish it had! Would make my job a bit easier and the carbs a little faster. Jim

Re: Stocker carb, removing choke plate ok ?
 

Back some years ago at Sonoma. Nat'l....Westley bounced me in Tech for having bent my choke rod a bit so it did not restrict my primary Air Flow so much.

He then rechecked it in line before first round to make sure the bends were
exactly correct!

Re: Stocker carb, removing choke plate ok ?
 

And the good news is Wesley is back.

Re: Stocker carb, removing choke plate ok ?
 

Now if they'll just turn Wesley loose, make his word final, and give him the necessary resources........

Re: Stocker carb, removing choke plate ok ?
 

So they're going to do a spot check....after 3rd round of eliminations...with an entire day of eliminations to get done ..to see if he took his choke plate out? C'mon Mark I was referring to the initial tech Insp. The tech guy's aren't just there to catch people cheating They are there to answer questions concerning some of these items that maybe aren't clear in the rule book . Anyway he has his answer now and that's good

Re: Stocker carb, removing choke plate ok ?
 

Back in 95 at the Summers in E Town I was pitted at the far end of the spectator side as there were about 140 cars in stock and after winning 3rd round that Sunday afternoon we were told we had about a half hour to cool and be in the lanes for 4th round, temp was in the high 80s. I was heading around the outer lane to cross over to the spectator side when Wesley stopped me and thought it would be a great time to spend 20 minutes going through my carbs as well as other things. I had just enough time to reach my pit and fuel up and when I reached the staging lanes I was near boiling over. I had a great light and the better by far but the car died in high gear due to overheating and I ran a tenth off my dial flat out. I'll always remember Wesley.

Re: Stocker carb, removing choke plate ok ?
 

Tech can look any time for a spot check. Engine, fuel, wires, brakes, drive shaft, e-shift, and my favorite, the search for loose weight.

Tech in my opinion does two major things at the track: Help keep all of us safe by looking at our safety equipment. Making it mean something when win or loose a heads up race, or any race, by enforcing the rules.

I think they love the sport as much as we racers do.

Re: Stocker carb, removing choke plate ok ?
 

After reading this thread, now I know why efi cars are so fast! They don't have a choke flap! lol

Re: Stocker carb, removing choke plate ok ?
 

AND...…..

They don't do an initial tech inspection at National Events.

Since the driver is responsible for the car being legal and the driver has to race at Divisional Events to enter National Events. Therefore NHRA makes the assumption that the car will be legal at National Events.

Borrow a car to race at a National Event and you might get a suspension for something you had no knowledge of.

It's happened before.

Re: Stocker carb, removing choke plate ok ?
 

What? We have been teched at every div or natl before we can make a qualifying pass since we started doing this. Whether it be in the lanes or somewhere else. Hood open,hatch open,both doors open,tech card,nhra membership, jacket, and helmet in hand. Ready to answer a question and ready to correct something they dont like.

Re: Stocker carb, removing choke plate ok ?
 

Did they look at anything other than safety equipment????

That's not a tech inspection that's the NHRA trying to avoid a lawsuit in case you are injured.

Getting "teched in" does not automatically make your racecar legal....

Re: Stocker carb, removing choke plate ok ?
 

I don't know how we could get anymore "teched" that process sends us on our way to qualify and race. They usually look at a couple things extra. Of course I realize they can come back at anytime and check anything they want to. This thread is beginning to run in circles.........

Re: Stocker carb, removing choke plate ok ?
 

Ya know, more velocity = more air speed. Some people would say, try two choke plates.
