Hi, I've got a Benge 290 with aftermarket Thayers installed. I've just got some questions about the horn in general.

1. Is there a way I can test the seal of my valves at home, to make sure they're fully sealed?
2. One of the Gb lever linkages is broken, it was plastic. Can I source a link for any Thayer valve, or does it need to be brand specific? The valves say "Orla Ed Thayer"
3. The Gb lever is a straight paddle, and doesn't really work with my hand. Does Edwards offer their Gb levers as a separate purchase, or does anyone know of a company that can do such a thing?

Take it in to a good tech and they can do all of this stuff for you.

The stock Orla Ed Thayer valve uses plastic cup type sockets, which can be purchased at most hobby stores:

You can test the seal by taking off the handslide and tuning slide, blocking off the tuning slide inner connecting tube with your finger, and blowing into the bell receiver. If the valves are leaky you will probably hear air escaping when you do that.

When one does this test, should one also remove the tuning slides from the valve section(s)?

Nah, leave them in.  You may also want to engage each valve and make sure there is a decent seal on both passages.

If you do have a leak and you can't find it, drip some soapy water (snoop!) around joints or threads or the spindles.  It will bubble where the air is leaking.

Cheers,
Andy
