OK, just spent the last 3 hours (3.20am here lol) messing around (with a bit of riding in between and found a few things.
1. Don't lose the peice of plastic between the carb & TPS! I dropped it and have spent the last 2 hours making a replacement!
2. Unplugging the RC valve servo gets rid of the permanent red warning light.
3. With the makeshift slot I made I have no red warning light (with the servo disconnected), until I get to about 1/2 throttle, then the warning light comes on. If I make adjustments either way the warning light comes on at 1/4 throttle or 3/4 throttle depending on which way I adjust it but during the last 2 hours of adjusting I never got to full throttle without the warning light appearing.
I'm doing all this manually, without a DVM, I had too much redbull tonight so had to do something.
Have I completely wasted my time trying to set it manually as it seems like no matter what adjustment I make the red light comes on at some point in the throttle?
