My carb. setup is HSN: 1 turn in from flush and LSN: 2.75 turns in from flush.
I have made Side-by-Side comparison with AXE Rossi m21 3 kanal (low budget engine)
http://www.modellbauversand.de/e/pi218/pi27/pd170.htm and I didn't notice any difference. Acceleration & top speed are same.
I have expected little more from Go engine
What pipe are you running ?
Do you have the long needle LSN with these settings ? If you have the older short needle these settings will be way to rich on the HSN.
For the long LSN your settings sound about right. Maybe a little lean on the HSN, but that depends on pipe, how run in engine is etc, etc.
I run a 7.5 mm blue Go restrictor on my stock 7 Port Turbo and it goes great. I haven't done any side by side direct comparison with other motors (only going down the straight at my local track when racing, and the 7 Port comfortably holds it's own against other more expensive motors).
Running 0801 pipe, HSN 1/2 to 3/4 in from flush depending on conditions, LSN 2 1/2 to 2 3/4 once again dependant on conditions of the day.
