I am using an NGK plugs. It is a heat range 8 plug but I still seem to have some carbon fouling going on. The carb seems to be setup good as the plug are no longer gas fouling. Should I go to a hotter plug?
I ended up buying another mighty demon. I am sending the first one in for service. I left the 71 and 79 jets in the new one, put in a 4.5 or 5.5 (can't remember off hand) PV and it works very good. I still need to tune the PV by using a vac gauge, but I am very pleased.Kerry we talked awhile back on carb set ups. What did you end up with for jets and PV #'s?
I'll check to see what plugs ford put in my 347. thanks
