Here's what I would consider a stupid question:
I've recently replaced the power valve and the needle-seat assemblies.
Can I just get by with what is essentially the gasket kit, or should I go and buy the whole hog rebuild kit?

(it's a stupid question, because I know I really should pony up the extra to get the complete kit... but I'm happy to save a few bucks if all I'm likely to need is gaskets).
