If the spark plug is not gummed up then it wouldn't make a noticeable difference. My only suggestion would be to remove the governor on the engine because you cant change the gears inside the reduction box as far as I know and you might find it hard to get a new pulley for the axle.

so is there anything i can do to the reduction box to make it a little faster also do you think a new spark plug will do much of a difference

No, don't touch the reduction box, alter the external gearing (see my last post).

A new spark plug can make a little or a lot of difference, depending on the age/condition of the existing plug. A visual inspection will answer that question. If it looks ok it probably is; just clean the contacts with a points file or light sandpaper. If the electrode is worn away then you should probably get a new one
