Moving to another topic, I see some drivers use an oil filter between the tank and the carb, but some drivers don't use it (I'd say most pics of the pro's cars don't use it).
Any reason why NOT to use one? I heard something about using it provides more "even flow" of nitro to the carb during certain seasons (or this is mere snake oil tomfoolery BS that's being whipped up?). Any one have any opinions on this?
