TNT last night

hay moper I have a little mini on off of a dakoda but its about 8yrs old and i think thats the problem... i had my batt. out of my dump truck in the car and it just would not start took batt. and had it tested it fine crank dump right up....so its time for another starter or rebuild this one.....but hay i only paid 30 buckes for it.....i plan to block the pv in the back of the carb could someone exp. how it should work I know it stops it from pulling gas as it runs down the track at full but should I also change anything else?I checked my plugs after the run and they are a tan brown on tip and no spicks on the porc. so I think that im about right....72fr/85bk 4.5pvfr/6.5bk with the pink cam and 31 nozz. its a 950 hp sealed to the hood.....and with 110 race gas the plugs are a nice looking gray ....i mixed it at the track about 5gal 97and 2gal 111....oh and as far as a batt. which optima did you use moper...the yell.??
