Default Burner on Bryant furnace won't come on

Hi all,
I have a Bryant model 397H (1980's). The Furnace (AC actually) had a condensate leak last spring and I replaced the Main Board and the wiring harness. Now (fall) I checked Heat functions for the winter and discovered the main burner won't ignite. AC functions are fine. When you call for heat... the inducer runs, the pilot ignites but thats all. The Pilot continues to spark for about 25 seconds and then the 3amp (auto-style) fuse on the main board blows. If I pull the Green wire from the MFV (main fuel valve) then the igniter stops and the pilot continues to burn. I show 26V on the brown wire at the mfv. I jumpered the orage wires (resetable draft switch?) and the red wires (over temp) with no improvement. Any one with Bryant experience have any suggestions?

Thanks
Adam

Default I Fixed it

Well I read my own post this morning and realized that the short that took out the circuit board and the wiring harness probably shorted the fuel control. I replaced the fuel control ($125 ouch) and all is well.
Thanks to anyone who was pondering a response.
