I use the roto start on my savage w/ WASP 26... no problems... WAY easier with simple push of a button.. tuned properly you only have to tap the button to start it.. i never had a problem with it.. you can break your one way bearing if you flood your engine and hold down the button for a long time... for me if it takes more than 2 seconds to start I stop it and check to see if the engine is flooded or no fuel at all.. you can really tell by the sound of your engine... I guess I know my engine real well to know... just know your engine..
