     Hi Ed
     Did you try the B9EV plugs? 10 hrs! what do you use for fuel? Nitro? Are the BUR plugs surface gap? If so after 'plug sag' (sounds like a new disease) get a 500volt megger and check if you have conductive lead on the insulator. How's the fuel flow gadget coming along?
     Have a beer for me.
