Your company provided everything you advertised and met my needs. Can’t ask for much more than that! Thanks.

California – Suzuki Samurai
It was a pleasure – The internet purchase was easy. The price was competitive. The product arrived promptly. The product worked as it was stated to work. My old carb was easily returned in the box with the return label UPS provided.

Maryland – 33’ Carver
Very easy to deal with your company. Spoke with your reps on the phone and they were very helpful. Shipment of the carburetor was quick and the core refund was quick as well. Thanks for quality work.

Georgia – Chevy Truck
I could not be more pleased with the customer service and the concern for customer satisfaction displayed by your company and your employees. Truly professional in every sense. You’re a credit to the industry.

North Carolina – Ford
It was a pleasure doing business with you. The carburetor works great and the shipping was very fast. Thanks again.

Oklahoma – GMC Truck
The carb works great. Thanks a lot.

Texas – Mercruiser
I have been looking for this carb for 2 years to finally find you guys!! The internet is amazing, but you all are incredible for having an exact match carb for my 38 year old Sterncraft with a 38 year old 2 barrel—140 hp mercruiser in it!!! That boat ran better last week than it has in 20 years!! Price and service were excellent, you people have made this old man very happy!! Hopefully you will rebuild my old original and make somebody else as happy. Thank you very much.

Nebraska – Nissan Pickup
We are a new car dealership and repair facility. We were very pleased with the carburetor and with your service. If we see the need for another carb in the future, we will definitely check out availability with you again. Thank you for the service.

Arizona – Ford F-150
When my carburetor failed, my mechanic told me 1976 carbs for my truck were no longer manufactured and told me to call around to junk yards to try to find one online. When I brought yours back to him to have it installed he was very impressed. And it works great!

Washington – Toyota
Bolted right on. Runs like a top.

Louisiana – Ford Truck
I was certainly pleased with the service and the fact that a carburetor for a 27 year old vehicle was available and came set to perfection! I have locked your web site into my favorites and will pass along all who ask me where to get a carburetor. Thanks for the service and have a blessed day.

Kentucky – 32.5” Carver
Over the winter I purchased a remanufactured carb for my 350XL Crusader engine. That engine has been lazy and hard to get to run consistent since I bought the boat (used) 5 years ago. I put your carb on and the first thing that impressed me was how quickly the engine started and how smooth it idled. Today I took it out for the first time this season and that engine ran the best, it has ever ran. It was so responsive and I could tell a definite difference in power. Now the port engine seems to be the weaker one ( I replaced that carb when I bought the boat, but may buy another one of yours for it). I did not have to touch any of the settings, mixture, idle speed, nothing! I put it on and am good to go! However your company does it, please keep it up! I am very picky on how my boat runs (and looks) and could not be happier with your product and service! Thanks for doing what you do and it is so nice to have someone in the marine industry really care about it’s customers.

New Jersey – Larson / Mercruiser
I was very pleased about talking with your service before my purchase. Your website was outstanding in order to properly identify the carb I was ordering was correct.

South Dakota – 1987 Pontiac Trans Am
I just drove to Colorado 2 days after installation. It ran great ( no service engine soon light.) Averaged 25.1 MPG.

California – Jeep Cherokee
It was a pleasure to do business with this company. I found them on the internet, called and they knew what I needed. Also the price was great, best deal I could find, and I‘m a cheap person, so you know I looked around. Fast and courteous service. I’ve already referred people to them.

Oregon – Toyota Corrolla
Worked right out of the box! Thanks.

Arizona – Chrysler 5th Ave
Your service was fast and the website was good, efficient. The carb is working fine!

New York – Chevy Caprice
Great Experience. Your help on the phone prior to ordering was great. You shipped the carb and it arrived as promised and the car now runs great. All this for a good price. If I need another carb you’ll be my first call.

Virginia – Ford Industrial
I wanted to let you know I received my carb for my Ford 300 Industrial from you. The rebuild job was great. It looks like a new carb. I bolted it on and it started right up and runs great. If I ever need carb work again you will get the call.

Tennessee – Chevy Caprice
I would like you to know that your service was excellent. The carb arrived on time, looked good and fit properly. I like the fact that you test and tune every carb on a real engine to customer specs. Your rebuilt carb is the reason my car went from emissions, twice the legal limit to half the limit. Your prices were reasonable, far less than buying new and even less than several questionable E-bay carbs. Returning the core was a breeze. Thanks for your quality work.

Colorado – Dodge Ram D-150
I was very pleased with your service. What a difference the carb made on the truck, it runs great now! Thank you!

Florida – Toyota Truck
Just wanted to say thank you all for the great service, product and price. The price was ½ of what NAPA wanted and beat other internet sites by a mile. I ordered the carburetor late Saturday night and it arrived Tuesday afternoon at 4pm. Had the carb installed in no time and it made my rebuilt engine purr, no adjustments necessary. Oh yeah, very easy to return the core also. My mechanic friend was impressed and I’ve had two people inquiring about your site… great job guys, I’ll send you more business. Thank you.

Texas - Suzuki
Everything about the transaction was top shelf. Carb was repaired and returned without question, even though the contamination was not your fault. Thanks

Wyoming – Nissan
I was very grateful to have found your company. I’ve been struggling for a few months trying to locate a carburetor with reasonable prices. As it turned out, that was the problem with my vehicle, so I thank you very much.

California – Mercruiser
The carb went on easy. My 11 year old did it! The boat started right up, he was impressed! We can’t wait to get the boat in the water. Thanks.

Alaska – Jeep
Great web site, and professional service. If I need another carb in the future I will definitely return to Guaranteed Carburetors. Thank You.

Washington – Toyota Truck
My experience with your company was excellent. The rebuilt carburetor you sent me works perfectly. I would recommend you to anyone wanting to replace their carb. Thank you.

Virginia – Trojan Watercraft
I have purchased 2 carburetors on 2 occasions for a total of 4 carburetors, also I have referred you to several friends which I know resulted in a sale. The carbs were correct and performed great. The service was prompt and efficient, and the price was good. Guaranteed Carburetors got it going on right. Thanks.

Pennsylvania – Horse
A little neglect may breed great mischief. For want of a nail, the shoe was lost; for want of a shoe, the horse was lost; and for the want of a horse, the rider was lost
Benjamin Franklin (1706 – 1790)
Good advice from one of our country’s founding fathers. – Our tip: Regularly change your fuel (water separator and gas filters). Clean fuel is essential in maintaining your carburetor and horsepower.
