Today was my first chance to fiddle with the tuning since the last time out. I did adjust the high speed needle so it's running richer now. Video below shows a quick clip I took - wasn't able to open it up to full throttle (only have two hands and didn't want to risk it launching of the table), but off camera I did get it max a full throttle quite a few times without it dying. So, it now idles well (doesn't die anyhow), I can give it varying levels of throttle and it keeps running, there's a lot of smoke now, and it sounds epic at full throttle. Not sure the neighbors love the sound... but that's okay.
It was 72°F when I was outside, with barely a breeze. I used my heat gun to get the engine warmed up to 210°F before starting. At idle, the temps were between 170-180°F. After running with half or so throttle for a while, temps were in the 200-220°F. And after running at full throttle for 3-5 seconds, the temps were between 240-260°F. I didn't want to run it too long at full throttle since there wasn't any air moving through the heatsink.
Will see if I can get it out for another run to see how it does with this tuning. I assume I'll need to tweak it a bit to be optimal, but I'll be happy if I can simply get it to run reliably.
Cheers!
Your low and on the other hand seems to be on the rich side because there's too much fuel loading up.Today was my first chance to fiddle with the tuning since the last time out.

Here is my tuning video to you.
Everybody else they think it's a bathroom so I guess to everyone else here's my bathroom video.
Thank you for the compliment, my whole intention was to help this guy because I understand where he's coming from. Because has a beginner 10 years ago but I couldn't find no information from nobody and was getting mixed information from people.Got to admit ,your engine sounds good ,crisp & clean!.....
