Hi. I have a mammoth ST. it was in the shop all day yesterday and i got it back today. The problem was that it wouldnt start because it was slipping. So i took it in the have the one way bearing cleaned. The hobby shop said that there was nothng wrong, to take it home, fully charge my roto start, and my glow plug, and try to staty it. after doing both of these things, it still didnt start! i am supposed to take it to california with me tomorrow for thanksgiving!!!! PLEASE HELP!!! I have check every componet n the engine, and so has the hobbyshop. ANY IDEAS!!?

How about check the battery connection in the roto-start. If it is connected backwards, it will spin the roto-start backwards causing the one way to spin rather than engage.

Or maybe your oneway bearing is shot. You might have to repace it.

the one way bearing may have a crack in it or the outer caseing may be spinning on the inner part.when doing a visual check and a check by turning it with your fingers it will work fine but slip when useing the rotostart..id replace the one way and see what happens.

If it's not craked. Maybe try cleaning it really good. And reinstalling. Sometimes when they get greasy they slip alot.
