About Our Carb Service

Most people would throw these in the trash!  If you're carbs look like this, send them to 2-Smoke!

2-Smoke, LLC started as a mail-in carburetor service at the start of the COVID-19 shutdown.  Many people decided to purchase older performance two-stroke jetskis to pass the time.  With businesses shut down and dealerships refusing to work on older these types of machines, 2-Smoke become a business to serve the growing community. 

In addition to offering mail-in services, Brian, the owner of 2-Smoke, dedicates his time educating others on how to properly rebuild PWC parts.  With a background in education and leadership, Brian has created several DIY videos providing detailed explanations and demonstrations.   Fast forward to the end of 2025...To better serve the community, 2-Smoke has begun offering quality jetski parts at prices that beats the rest of the competition!

Carb Rebuilding Process

The process of carb building is three-fold:

  1. Cleaning
  2. Assembly with OEM rebuild kits
  3. Bench Synchronizing

1. Cleaning

A variety of cleaning techniques are used to clean carburetors.  Depending on the condition of the carb, cleaning strategies can range from gentle, such as detergent and ultrasonics, to more aggressive means like media blasting.  

2-Smoke's media blasting capabilities include soda, aluminum oxide, crushed glass, as vapor bead blasting for reconditioning surfaces.  Additionally, some parts require machining.  

This fuel pump showed severe pitting and required surface refacing and reconditioning.  Here is a before and after.

Outer surfaces can also be stripped with media and recoated.  We use a quality primer, base, and 2K clearcoat to protect the carburetor from harsh environments like salt water.  Brackets, choke plates, and throttle plates can also be polished to provide further protection.

2. OEM Mikuni and Keihin Rebuild Kits

Each rebuild will include brand new OEM parts that are guaranteed to work efficiently.  Furthermore, every rebuild includes new needle/seat valve assemblies.  If needed or requested, jets will be replaced.  The OEM internally screws will be replaced with stainless steel fasteners, which provide superior corrosion resistance.  

 

3. Bench Synchronizing

To complete the rebuild, each set of carbs will be pressure tested (Fuel pump, pulse cover leak-down, and pop-off pressure).  Pop-off pressure is a bench test to when the needle valve opens.  Each carb in a dual and triple set are required to have the same pop-off pressure.  Along with pressure tests, the high and low speed adjuster screws will be set to the correct setting for all stock set-ups. 

If your ski is not stock, you will need to provide as much detail as possible (engine mods, exhaust type, flame arrestors, etc.).  Settings will be determined by common practices and tribal knowledge. Fine tuning on the water will be required.  A tuning manual will be provided upon request.
