Berryman B-12 and Carburetor Cleaning Do’s & Dont’s

Share This Post

I have several carburetor cleaning videos on YouTube, and thought I would share some tips based on the comments I have received. Often times people state the they have cleaned the carb, yet they did NOT disassemble the carb, or remove any jets. As a result, they are stuck with the same issue. So please watch the video and read the tips below to ensure you clean your carb properly.

Make sure you use a high quality carburetor cleaner. My favorite is Berryman B-12 Chemtool which seems to have the most cleaning power and also has very good spray pressure.

You can buy Berryman B-12 Chemtool on Amazon.

 

Do’s

  • Verify all passages are clear. Use Berryman B-12 to ensure passage is clear, follow up with 90psi compressed air.
  • Wear nitrile gloves and safety glasses.
  • Hold jets with small orifices up to a light source to see if it is clear.
  • Use Berryman Chem Dip on heavy varnished components.
  • Use JIS screwdrivers to avoid stripping screws. These are my favorite.
  • Print service manual and/or parts diagram to help assembly and verify correct parts used.

 

Dont’s

  • Just spray carb clean at a half disassembled carb. You will regret it the results. There are no shortcuts in carb cleaning.
  • Do not get carb clean on rubber components.
  • Save the refreshments for when you complete the job.
  • Assume everything will be correct. People love messing with carbs and it may not be correct.
  • No sealer of any kind is supposed to be used anywhere on a carburetor. Buy new gaskets instead.
  • Paint or powdercoat parts that will be in contact with fuel. The fuel will eventually attack the paint.
