I havent even touched the needles. My ears are not good enough to note the difference in the sound in doing this, so I had one of the more experienced club fliers set the engine up and he and a few others were ok with the needle positions. So I am not sure how to set the ignition timing etc. ..................................
It's not the sort of ign timing you can set like moving the hall sensor. What we're discussing is the timing 'curve' built into the ign module itself.
The way I set up the throttle is I held the carb arm physically at approx middle of its motion range and then adjusted the stud servoside at neutral to get the position. ...................
Go back to my other post with the photo of the throttle linkage, and re-read my description. It's not about "middle of motion range" but rather the linkage as mounted to the servo arm (closer to the shaft) and at the carb arm (farther out on that arm).
How do you check the number on that ignition (where is it written)?
On mine it's a tiny round stick on in the lower right hand area on the face of the ign module. It states "4#"
Just above the dle web address.
True, but why spend the extra on an issue that's NOT really an issue?
Get your throttle geometry correct, set the idle to 1700-1800 rpm, and be done with it. IF you like, setup the 2 idle off a switch as I mentioned earlier. You can set the idle with a basic tach.
I already have expos of the throttle, almost 90% but that will only soften the center, it cant do anything regarding the sudden surge at the end of stick movement

True, but you asked about a throttle curve on a tx that doesn't have such, so I mentioned the next best thing.
Going to your 8FG won't cure the issue, it'll only give you a throttle curve.
Correct the idle, fix the throttle geometry, and (optionally) set up a 2 step idle off a tx switch (IF you like).....problem solved!
Now, go fly the daylights out of it!
