I've got the rotostart version as seen here. The oneway bearing is behind the backplate i.e. inside the engine block.
Has anybody have trouble with the oneway slipping from the oil in your fuel?
I noticed that it was slipping a bit when I first started it yesterday.

inside the engine block...hmmm thats new... or i miss something here...
for the slipping..yes it happens. fuel from the engine leak out to the one-way. especially using rotostart. due to the torque & fast spinning... it easy to spoil yer one-way bearing. whenever it can't be started.. check whether the engine flooded. STS got strong compression. u cant feel the tension when using roto. easy to break the one way. easy just clean out the fuel/oil. and if its new, try open a bit the plug like quarter turn to release some compression.
sorry, my english is poor.

Yes the one way is inside the engine block.
This is the rotostart backplate. And this is the one way that fits on the end of the torostart shaft. The oneway is between the backplate and the engine crank, with the little pin in the oneway turning the crank. So it is inside the block yes?
Just a little weird I think as the oneway bearing is external to the backplate on the stock savage engines.

Yes the oneway does sometimes slip due to the oil in the fuel. a couple suggestions to limit the slipping
1.. use a fuel with 12% or less oil
2.. always run your motor completely out of fuel at the end of the day.
3.. use an afterun oil to clear out the caster as thats what becomes gummy
4.. store your truck nose down so if there is some fuel in the one way it will run out.
