well then again see I DISAGREE WITH , and yes you disagree with me.....because my interest is not in the racing, my part of the hobby is in just purely doing everything,, And guess what i like just as much as running, my cars.....i love the cleanup, i like all levels of the hobby the same, and yes i like to get it started the best way that worked for me..........and know meachanically speaking the most quickest and direct route for air and fuel is the mostappropriate, you dont have to give air bubbles time to settle, if there is no air bubbles, now if you racers dont have attention to detail to ensure trouble/ air free operation exist well guess what continue doing what works for you, but have the hobby is sealling up the low of luel, one you prime the fuel line by spinmning the fly wheel, guess what....theres no reason, for fuel to be getting trapped in your fuel line.....because you ensured a good seal, so if you want to give your air bubbles time to settle by lengthening your fuel line, go ahead...but either way that fuel with the settled air in it will go threw your carb....and you never be able to accurately set up your low/ and high needle needles, because instead of having just fuel coming throught the fuel line, you will have air entering the car throught the fuel and air intake, so then yes youll have to much air to fuel ratio, and yes guess what these aare not V-8 big blocks those few little air bubbles you wanted to settle....yes will be cause to much air over fuel ration burning in your cyclinder.....
