Run-in Procedure for The Briggs 206 Engine

The 206 engine ships without oil. There may be a small amount of oil residue in the crankcase. This would be from power testing of the engine. Only use Briggs & Stratton 4T Racing Oil by Amsoil. Using automotive or other karting oils can have very negative consequences. There isn’t another oil that will offer better power output or protection.

Note that many of the break-in opinions on the internet are based on outdated information and incorrect beliefs. Here are our break-in recommendations:

Step 1

Add 400ml or of Briggs & Stratton/AMSOIL 4T Synthetic Racing Oil

Drive kart for 10 minutes at varying RPM but no more than 5000 rpm. This can be done on a kart stand if required. It is best to have load through applying brakes at times.

At this point, drain the oil while hot. This will keep any break-in particles suspended in the oil and easier to evacuate.

Step 2

Add fresh lot of 400ml of Briggs & Stratton/AMSOIL 4T Synthetic Racing Oil

Drive kart for a further 10 minutes at varying RPM but no more than 6000 rpm

At this point, drain the oil while hot. This will keep any break-in particles suspended in the oil and easier to evacuate.

Refill with 400ml of oil and you are good to go racing.

After an hour of operation, check the valve lash (as per Brigg’s specifications). Heat cycles help parts relieve any stresses held in during manufacturing. In our valve train, this usually opens lash slightly.
