Super Jet Return Fuel Line Restrictor - Yay or Nay?

[Parsonsjb88]

So a @BRANDO6X and I are trying to figure out if we need a fuel line restrictor (with changeable jets) in our return fuel lines or not? We are both using SBN44 carbs with the stock/oem fuel restrictor build into the return port of the carbs. We are both going to be running a/m pipes (b pipe and Nynja), high comp, overbored to 718 and 735cc, ported cases and cylinders.

What is everyone's opinion on running these a/m fuel line restrictors? Leave it as is with stock restriction or use the a/m ones and change the restriction?

You don't need to try using jets to complicate your setup.. Use the existing return restriction built into the carb.

One of the best engine builders advocates drilling out the returns but you are running small motors so I'm not sure if it's worth the trouble.
