Is there any way to test to see if a bearing is the cause of engine always leaning out no matter how rich the carb is set.

Thanks

Usually if the bearing leaks out nitro or after run oil it could be a sign that the bearing also leaks air. I have heard of some guys on the Traxxas Slayer forum say that they use ceramic bearings and avoid that problem. I don't remember who makes them or which model # they are but that problem has been addressed on that particular forum. I have not been around this forum long enough, nor have I searched that problem on this forum. It might be here, somewhere. It isn't much help but I hope it gives you another place to look.

the bearing does'nt actually seal a vacum,the crank to block clearance with a film of oil provides the seal.some of the 3.3 traxxas engines i've messed with came with excessive clearance so it took a sealed bearing to fix the problem[mostly from boca bearing]you can spray nitro cleaner around the suspected leak area with the engine running and it will either speed way up or instantly die.
