My 4 stroke kart club already runs World Formula but may now consider inclusion of Junior 206 and Animal in a couple of other classes. To help evaluate, can you provide further details such as HP and max torque/torque charts for each engine?

Asked by: Greywolf
The Junior 206 has approximately 8.8hp and is digitally rev limited at 6100 RPM.

what is the age range for these?

Asked by: Gaberacer4
The Junior 206 is rev limited at 4,100 rpm and comes with two slide options to be comparable to the Comer engine used in the 5-7 year old kids kart class. Unlike the Comer, a racer can simply change to our standard 6,100 rpm module and progress up the racing ladder system with just the simple change of carburetor slide at tracks using our 206 crate engine program as they advance in age.

why dose the engine not come with air filter or fuel pump fitting and a install manual

Asked by: nyza
The engine does not come with these parts or manual as this engine is to be used for sanctioned racing only. The filter may need to be changed depending on the sanctioned event.

Our engine is brand new. It will start and then die again rite away. Now the engine will not start at all and pops how do we fix it or get it to run?

Asked by: Owen69
Check to make sure you have fresh fuel. Fuel can go stale in as little as 2 weeks and cause the passageways in the carburetor to clog. You will want to change the fuel and spray the carburetor with carb and choke cleaner.
