do you know what the temp of the engine is? Anything below 190ºF, or about 95ºc will make it do this. Also, anything above 240ºF or something around 110ºc will also do this as it's starving for fuel. If you don't have one, I would highly suggest you get one.
However, you can try to adjust the high speed needle one hour at a time, starting out by going rich. There should be quite a bit of smoke coming out of the exhaust. If there is no smoke, then it's too lean.
As long as there is still smoke coming out of the exhaust, you can go lean one hour at a time (CW) and try it. Remember though, you can over do it and fry the piston. I have went so far as to burn a hole in the piston during a race that I "needed" to win, so I leaned the hell out of it lol. Just be careful.
Yeah bro, post it up. Love seeing people having fun with these things. Oh, and if you can post a video BEFORE adjusting, that will get me a pretty good idea of what way you need to go. I warn you though, it may be a while before I reply. Have to work tomorrow.
Right on, I will be looking forward to it. Getting kind of stoked into getting into this hobby again myself. Gotta love work and family life.
I know where there is a T-Maxx for sale. Just need to talk the guy down on the price lmao. And "the guy" will be in here soon, I'm sure lmao. I already have the Tx for it too. Running the DX3R, same as I ran on my losi truck. But, I'm more into helicopters and planes than ground pounders now. I know, need to get back to what got me into this hobby. Working on it lol.

It sounds like the bottom end is lean and the top end is rich. I would go CCW on the bottom needle about 2 hours, and go CW on the top needle 2 hours and give it a shot. The idle seems high to me for a .21.
I say this because it seems to want to jump off the line like a bat out of hell, then loads up. The top needle setting that you have now is exactly what you want when breaking in a new engine, or piston and sleeve. But, for max fun, lean it out. You will hear it "get up on the pipe" and just start singing to you at WOT. It's a beautiful sound.
Keep posting the videos. Can't believe you did this in the middle of London hahaha. That's great.

If your servo has a metal gear (and being an 1/8th scale, I would hope so) then yes, you can use thread lock on it. But, if it's plastic gear, don't do it, it will melt the plastic.
And yes, that lower left picture is the low end needle and the top left is the top end needle. The top right, they are not kidding, don't ever turn that one if you have a 3 needle setup. And the lower right is your throttle adjustment. The carb should have an opening of 1mm or so at an idle while looking down the bore.

HS645MG, that is your servo number. The last two letters stand for Metal Gear, so yes, that is one you can, and should use thread lock on.
Picture 4 and 5 show no back pressure hose on teh muffler. This MUST be run at all times to pressurize the tank. If that comes off, or if the exhaust comes loose, you will go lean really bad.
