Is this too dark

[blade25]

this is almost 3 hours of run time, should the gp look like this? I gave it full throttle quite often in that run time. No rough Idle, I c nice smoke trail, good tske off. What do you think? Is it still to rich? What should a properly tuned gp look like after several runs?

I'm afraid of popping another gp. I have already popped 4 on 3 quarts of nitro

Your running to lean, see how the coil is very bright.

should i adjust the hsn only? My low speed I think is good when I pinch the fuel line close to carb it shuts off in about 3 seconds. after about 2 secs it revs up another 2 sec and then it shuts off

The low end sounds about right. Richen the high end and try again.
