Hello again, I just got her running again this evening. I was waiting on the starter to be reconditioned since I was last here. Started first turn with a jump start but as soon as I took the jump leads off it started to backfire & miss before stalling. Jump started it again & it ran smooth but as soon as I took of the leads off it started to backfire again and stall. I know the battery is shot but before I done the head gasket it ran smooth after it was jump started? Any ideas guys as to what could be causing this.........
