New Walbro Gasket Hard, Won't seal

[denn]

It's been awhile, I still didn't get my 360 together, I hope I can do better with this one.

I have a Super2, with Walbro HDC 65 carb, #17 pump gasket leaks, I can't get any thing on the test gauge.
The old gasket holds, but its rubber or neoprene. Can I soak the new gasket in something or put heat on the cover when together to get it to seal.
Thanks

I use Permatex Gasket Sealant on leaky modern gaskets...it works well.

Usually soaking in brake fluid softens rubber. Soaking stiff diaphragms in brake fluid is a nice trick to save a few dollars on carb rebuilds. Many gaskets though are paper, not sure what brake fluid would do on them.
