Has anyone drilled a water drain hole in the low point of air snorkel? I recently had the RV-7 outside during a heavy rain storm with cowl plugs in. Water got through, through the air filter and down into the manifold into the spark plugs. Major pain in the butt to get all of the water out. Also has anyone modified the snorkel for a better low point water drain. I also need to install sniffle valve, but have very little room above Vetterman exhaust. Thanks.
