We are phasing out our Carburetor Sleeves, except for the 33 to 28 sleeves which we use in our 11.90 Pea-Shooter Combos. If you're looking for Carburetor Sleeves, call now to see what is remaining in inventory. Available while they last!

Huddleston Performance is proud to introduce the latest in Carburetor Innovations yet again. Our new Carburetor Reducer Sleeves don't just benefit one group of racers, but rather cover the entire spectrum of Jr. Dragster Bracket Racing. Over the course of the last few seasons it has become increasingly more common for people to need help slowing there big motors down. In most cases we've had to start by selling the racer a new 33 Mikuni and then possibly even selling them the reducer sleeve to further slow their combo. We've had good success using the 33 Mikuni on literally everything from our Pea Shooter 12.90 all the way up to our 3 1/2 Heavy (for 8.90!!). All the while it has bothered us to have to sell someone a new carburetor when they only need it for slowing down purposes. At some point it became obvious that the better option for the racer was to just reduce the size of their existing carburetor. One thing led to another and now we stock 9 different reducer sleeves for the 4 most common Jr. Carburetors.

 

1. 28 mm Mikuni Reducer Sleeve

 

This reducer sleeves a 28mm Mikuni down to 24mm. It's purpose isn't so much to "slow" an engine down but more to simply pick up the velocity in the carburetor to make the 28 more tune-able on 12.90 type motors.

 

2. 33 mm Mikuni Reducer Sleeves

 

The venerable 33 mm carburetor is literally used for every application one can think of in Bracket Racing. What we've seen is that there's a need for more than one size reducer for this carburetor. We now offer them in 28mm, 25mm as well as 22mm hole sizes. The larger ones seem to work well when trying to simply take weight off of an 8.90 car. The smaller ones will do well for various 12.90 type applications.

 

3. 40 mm Mikuni Reducer Sleeves

 

We've had a number of 8.90 racers contact us that have bought some sort of "7.90" motor that's equipped w/ a 40 mm Mikuni and they need to immediately slow their 400 lb package by a full second. That can be a tall order without somehow reducing the output of the engine. Until now we've only had the option of first selling them a 33 mm carburetor and then selling them a reducer sleeve for that 33. This gets pricey quick. We now have reducers for the 40 Mikuni in 36mm, 33mm and 30mm hole sizes. These should work well for helping to slow a 40 equipped car or can also be useful for taking some lead off of an overpowered 7.90 car.

 

4. 42 mm Mikuni Reducer Sleeves

 

These serve basically the same purpose as the 40 mm reducers, except they are designed to fit the 42 Mikuni carburetor. We only offer these in sizes of 36mm and 33mm. Due to the increased inlet size of the 42 we have some serious concerns that the 30mm version will lead to an unfixable stumble. As with everything we sell, we simply supply product we are confident will help racers win races. That being the case we only stock 2 sizes for the 42 mm sleeves, both the 36 mm and 33 mm will help slow your car down while still maintaining a level of consistency.

 

All of these Reducer Sleeves install the same way as our current 33 mm to 28 mm Restrictor Kit, for full installation instructions click here. They are very simple and quick to install, and depending on your application are very effect in a number of different ways.
 

As we pointed out earlier, not only are these great tuning aids, but they are also a very cost effective means for slowing down your ride. There are 2 ways of purchasing them, you may purchase them one at a time for $19.95 or you may purchase a set of 3 of ANY reducer sleeves for a price of $49.95. That means if you have 2 different racecars, one with a 42mm Mikuni and one with a 33mm Mikuni for example, you can purchase reducer sleeves for both cars in one kit if you need to!

 

These new Reducer Sleeves are a must for anybody trying to slow down their racecar. Regardless if your 12.90 to 7.90, if you need to slow your car down call us today to get a reducer sleeve kit.
