[C320-list] Drain aqua lift muffler? Engine won't start after charging batteries overnight

[kendgb]

I remove the whole pet cock and drain/vacuum the water out each year for winterizing then draw 8lts anti freeze Into engine and then drain muffler of antifreeze in same way.  The Flow is free and easy.  Ken Geiger Northern Dream #765. 2000Sent from my Samsung Galaxy smartphone.

  charging batteries overnight I've never had water from the muffler drain. Once I removed the petcock and inserted a flexible rod in there. It went in a fair distance and still nothing came out. As others have the same experience there could be some explanation. Any ideas???Warren & Pattie UpdikeC320 1994 #62 "Warr de Mar"Middle River, MD (Chesapeake Bay)-----Original Message-----From: Bob Borelli <cassattc22 at hotmail.com> Sent: Monday, July 6, 2020 7:28 PMTo: C320-List at Catalina320.comSubject: Re: [C320-list] Drain aqua lift muffler?

So, I'm guessing it is gunked up inside the muffler next to the drain hole.Dave Hupe1994 C320 (#32)Sent from Yahoo Mail on Android  On Mon, Jul 6, 2020 at 5:21 PM, Scott Thompson<surprise at thompson87.com> wrote:   The one time I tried to open the drain the whole thing twisted out ofthe fiberglass.
