stalls when gassed...

Well, I'll throw in my $0.02

Have you checked your accelerator pump?

If you don't know how, here's some simple instructions...

1) Remove air cleaner assembly.
2) Shine flashlight down primary throttle bodies
3) Pull on your throttle linkage (go from no throttle to full throttle fairly quickly)
4) You should see a small stream of gas shoot out across the throttle body. If you don't see any gas or only a weak squirt, you need to put in a new accelerator pump. Good news: They're cheap.
