The 418 number you mentioned is stamped on the jet and means it has an orifice size of .118. Same with 401. Opening size is .101. By the way, that .118 is a BIG jet for most applications!! It sounds like you might be talking about a #1407 carb which comes with 413 pri. 407 sec. and 71x47 pri. metering rods. I am still sorting out my jetting and timing requirements, but at the present I am running 410 pri. and 404 sec. with a 75x47 pri metering rod.This is working well at present but I wish I had better ways to adjust the accelerator pump shot as it still has a very small stumble if your already rolling and then punch it. Bear in mind that I am at about 1200 ft. elevation. These jets probably would be too lean at sea level. You can get tuning kits with several different jets and rods from Summit or Jegs and even O'Reilly stores or also individual jets and rods. Hope this helps !
