We now see that it's not a nut or drain bolt, it's a cap...Couldn’t get the nut off without the whole drain pipe turning…
They make them to fit almost all small engines, including yours. It would replace the entire drain tube. However, with the drain tube you have, perhaps a drain valve is the better solution.I cannot see that drainzit makes a tube that fits my Ariens engine.
Yes, no crush washer on a cap. Internal O-ring, maybe. Always lead with your make & model number to get the best answers up front.Went to several places for a crush washer...apparently my nut is not designed for one.
