The problem is the fuel. The engine was broke in with low oil lube 10% or less. and you switch brands 12% and still are using less oil lube.. The engine will idle erratic like that as the fuel is for racing not back yard bashing. Buy fuel with 14-18% oil lube and or a plug with a idle bar? The engine is now running lean loss of compression from the fuel oil lube and poor tuning.

All my information is FACT! not BS like all you other bozos keep posting. Breaking in an Engine with low oil lube and the switching oil content again can cause poor engine performance like this.

Breaking in an engine only requires 12% oil and that’s not even required for the full break in of the engine.

For REDS motors,TS4 or P4 plug helps with idle. You can't set a carb to a specific idle gap and have it work all the time. The part in the JQ video about balancing the carb is what you are after. Make sure the motor is at least 200* before you start playing with the needles. Sounds like you are fat on the bottom and the idle is high. If you know how to measure squish clearance, check to make sure you are 0.60mm or higher. If not add a shim. Factory setting for the carb are 3 turns opened from the
fully closed position for the HSN and 3 1/2 turns opened from the fully closed position for the LSN. Idle gap of 0.5 is approximate, but will set it self as you tune the motor.
