Someone tell me their engine settings on their TRX 2.5!!!
The tuning on each engine is going to be different. Not all engines run in the same temp range, plus you have to factor in the external stuff like temperature, barometric pressure, altitude.
What I would do is get some higher nitro content fuel first. Return all the needles to stock settings and go from there. Stock settings: HSN 4 full turns from all the way in, LSN flush with the inner ring, and idle screw should have a 1-3mm gap when the carb is all the way closed. Take off the air filter and look down the carb.
Mine is set somewhere between 4 and 5 turns out. The LSN is about half a turn in from stock, and my idle is set just like I said above. I use OS #8 plugs, and 20% nitro 18% oil fuel.
Keep at it!! You will get it eventually and it will be a blast.....
