I tried every combination 1 hour at a time one at a time. It continues to make the same noise with the idle going high then going low and girgiling off throttle no matter what I do. In fact the more I got into it the worse it became.
Off throttle the only way I can explain the noise is like a high pitched girgiling noise that sounds like is blubering and its loud. Its not a normal noise and becomes worse when it hits operating temps. No matter what I did it didnt make better or worse but more worse. The noise sounds like a clunker of an engine.
At $360.00 I am pissed!!!!!!!!!!!!!!!!!!!! I havent done anything to cause this problem no serious crashes nor have over temped it.
I am stuck!!!!!!!!!!!
I think your motor is not broke in yet your probably getting close.It is typical for this motor to run erratic until it is broke in. The factory settings pertain to using Trinity Platinum 30% fuel so running Byrons they will be a little different but not a bad place to start. leave your high speed fat for now and work on the bottom to were you can idle and hit the throttle and it will still blow smoke but takes off and then flattens out from being too rich on top. Don't try to set your setting on the box you need to put the motor under a load to tune and then you can dial in at your track. After you run around get a little temp in it you should start with your bottom end first then work on the top. When the motor brakes in totally it will richen up and you will need to re tune and then it will hold a tune. Remember this motor .21 should not need to ever get above 200 deg f my motors run around 180-190 all the time don't try to tune by temp tune by sound you should always see a little smoke all the times. Motors that flame out when you hit the throttle normally are too lean not enough fuel for the motor it will flame out and too rich will fuel wash the plug and makes crackling noise and then stalls. Hope this will be some help.
