The 6 corner hex one way bearing fits the pro.15 engine. The round with 2 flat sides one way bearing fits the 2.5 and 3.3 engines.
There are 2 different size/types of Traxxas pull starters and ex starts for the engines as well. The early type uses the 6 corner hex and is for use with the pro.15 engine.
The later type with the round with 2 flat edges fits the 2.5 and 3.3 engines.
It appears you may be running a Pro .15engine and will need the 6 corner hex one way bearing and the compatible pull starter. The One Way Bearings can fit either of the engines starter shaft but the pro.15 and 2.5/3.3 ez start & Pull starters are not interchangeable.
If you are running the pro.15 engine, the previous info about the carb baseline/stock needle setting are incorrect as well as they are different than the 2.5 and 3.3 engines.
Do you know what engine you are running? Have any pics of your setup?
