When yall coming out with some new up close detailed videos for these carburetors? I'm having all sorts of issues nobody seems to be able to figure out and all the fingers seem to be pointing at this carburetor I purchased from yall.

[SummitRacing]

Hi, it sounds like the problem is with the person you had adjust the carb. If it was running nice out of the box, something in the new adjustments must be off. You didn’t state which carb you have but we offer three excellent tuning videos. Each video covers tuning and performance upgrades. You’ll find out that you can do your own tuning.

Do u have to have the fuel inline or can u make one with hose and a t?

[Muleskinner]

Ditch the paper gaskets under the needle and seat adjustments right off the bat. Replace with nylon, makes for leak free float bowl level adjustments.

I have the 750 mech secondary from summit... worked ok with automatic th400 but switched to a m22 4 speed and nothing but major problems... changed every jet damn near... bought a wide band for adjustment.. tried all restrictors ( idle speed, accelerator pump) floats and all adjusted and just has bad hesitation especially at around 2000rpm... timing is spot on and tried adjustment with vac advance and wieght springs... I'm thinking I got what I paid for

[brianroftsc]

can these carbs be modded be used for a blow thru setup?

[SummitRacing]

The Summit Racing carburetors are not designed for a blow through application but, we do carry that type of carb through Quick Fuel Technology.

Can this work well with an external electronic fuel pump? Will it need a fuel regulator?

Too bad those 4010 and 4011s didn't catch on, they are a nice carb, easy to work on and tune, I have the 4011 650 spreadbore on top of a mild built 455 BBB and really responsive, I can launch without spinning tires most of the time and she pulls hard... smooth transition into secondaries. Been hunting for one of the larger ones to try out, ended up with a speed demon that was misadvertised, 850 when really a 650 so need to sell and try my luck again on eBay...

I bought the 500cfm version of this carb. Do you offer a kit to convert it to manual choke?

Hello. If I may ask, what could be the best carburetor for my Toyota 2E 12 valve engine? I am just curious if there could be a better carb than the stock for my engine. I am just asking if by chance there are still ways to help improve my engine's power and fuel efficiency.. This sure looks like a great carb.. c: 

[bootyman]

Speaking of carb size, why do you all not have a 500CFM version of the one in front of you? I have a mild 302, and a 500 would be perfect! I just purchased one that should be here tomorrow and I will be ticked if I find out you all have a 500.

Does anyone know if a 600CFM carburetor is good enough to run a SBC with a mild cam?

[lagosduarte]

What carb is better to put in my ls1 with the victor intake???

[alsanchez]

What should the average mpg on a Chevy 327 sb be with a electric choke 600cfm carb, , I just now seen this video and I took my truck to get the carb adjusted and it's so much bad and it swallows fuel it was so nice out of the box and now I don't know what to do

@0:52 the AN fitting wrench isn't even turning the nut. #justforshow.

For a topic as important as choosing a correct carb for your application, I think a vid longer than 2 min. and 6 seconds would have been more informative.

This guy telling me I only need a 550 for a 347 stroker. But a 600 was too small for 302 smh
