Default Pull-Start One-Way Bearing Not Catching

I am using a pull-start on a 18ss HPI motor. When I'm trying to start the engine most of my pulls are no-grabbing pulls. I mean that it doesnt turn the engine over at all. Then every say 3-5 pulls I will get a quick grab but usually not enough to kick over the engine... I've tried cleaning the one-way bearing and also have tried a little oil. But really no change..

Have you tried one-way lube?

I would just replace it. For the sake of $20-$30 it would save a lot of headaches

Forget the pull start once and for all. Buy a starter box!!!

The one way bearing has very tight tolerance requirements to function reliably. Sometimes a cleaning and lube will help, but this really is only a solution on race day when you have no other alternatives. Once it starts slipping, it usually means that the roller pinch guides are worn out and you have to replace it to avoid the headaches.
