Default Help with my rs4 3 rtr

I need help with my rs4 3 rtr. After I go full throttle then let off the engine revs up for a second before it goes to idle. How do I fix this? Also what should I set my needle settings to?

Could be your carb throttle arm is stuck. Do you have a rotary type carb? I had a problem with mine getting stuck too because the linkages were binding so I'd check for this.

Yes I have a rotary carb. But I don't see where it's getting stuck anywhere.

sounds like you are running lean, richen the hsn up a little bit, als do a search on tuning, you will find some articles, there is no set place for the needles to always stay at

I wanted to know what the factory needle settings are. And the high speed is already rich. It's spitting out alot of raw fuel out of the exhaust. It pours out of the exhaust it's so rich.

then lean the hsn needle out, you dont need to start from factory settings, just tune from where you are
