After parking out during heavy rain this week I got an unpleasant surpise.
It had been a week of heavy rain then freezing temps. When I went to start up the throttle was stuck. I dropped the cowls and to my surprise it was frozen with ice.
Water had come through the filter and down the snorkel. Past the butterfly and into the manifold. (horizontal induction)
Two things caused this. Firstly I didn't have a drain hole in the bottom of the snorkel. Second was that the sniffle valve was stuck and didn't let the water out of the manifold.
Even with a drain hole I'm not sure if it would stop all the water. I've got a replacement valve coming.
Has anyone else had a similar experience?
