Q-Jet Needle and Seats
 

Is there any difference between the standard version and the "windowed" versions. Do the windowed ones allow a more controlled fuel flow into the float bowl? With that said is there any difference in where to set the float level? Thanks, Randy

Thanks, Al. I 've also noticed that all the new ones come wthout the slots. I just thought it would be good to allow some of the fuel to come out the sides and not have it all shoot out the top of the seat. I know a few guys that machine their own slots in the new ones. Some of the local stock car guys drill 4, .110 holes, 90 degrees apart. I don't know if they are seeng a real difference or if it's just monkey see, monkey do. There isn't always alot of science when they do things. lol I'm just looking to find out if the Stk /Super Stock guys see anything. Thanks, Randy

Are you guys talking about the early 207 style carbs, or the 75 and newer vapor recovery models?
It makes a difference as to how the fuel enters the bowl area.

Mark, the carb I'm using is 1980, 17080202. I'm not really having any issues with it but I'm looking for possibly better setup. Thanks
