RE: PLEASE Help I am still having trouble tuning
quote from rchobby.org
Engine manufacturers often include base-line settings for the mixture needles, so it’s wise to start with these. If this information is not provided, then you must arrive at needle settings that will get the engine started. A universal starting point is usually about 1 turn open (counterclockwise) on the low-speed needle and somewhere in the 2- to 3-turn range on the high-speed needle. This varies among engines, but it gets you started running, and then you can make the necessary corrections. After the initial startup, follow the proper break-in procedure, then worry about performance tuning!
The proper sequence for adjusting the mixture needles is hotly debated. When you start to fine-tune the engine, it’s generally best to start with the high-speed needle, then set the low-speed. First, however, get your engine running, and keep it running before you worry about race tuning.
