Well I actually swapped it in and took it for a ride. It has great off idle and part throttle performance so I don't think i will mess with the primaries. I have this in a pretty much stock engine in a dirt track car that will see a lot of WOT. How will I know what secondary metering rod is in my qjet now? I'm thinking maybe I should just put the next larger one in to be safe. Putting in a bigger secondary metering rod will richen it up at WOT, correct?
