on my auto 200x I have the stock 200 carb on it and it runs perfectly and it has a 105 main jet with the dg krome power exhaust, then i wanted to get a litle bit more power out of it still, so i put the original 200x carb on it and it floods out if you leave the gas valve on, so i switched it back to to regular 200 carb, with the regular 200 carb the plug actuall lookes sorta blakish, and i have a dg krome power exhaust on it. so i am not changing the jetts in the carb beacuase it is already sorta running rich as it is, but i have needle clip at the leanest position at the top of the clip so maybee this acts like an equalizer type thing for that pipe. because when i had the pipe on originally it would not run worth a dam so i just moved the clip up or down till it ran great, and plus I just rebuilt the entire engine with new piston rings and gaskets and grinded the valves.
