This is whats happening, the LSN is rich but isnt getting the full supply because the HSN is so lean... what your experiencing is when you richen the HSN its letting the LSN get full supply its asking for, with it being so rich and then thats why its loading up and cutting.
again, You need to richen the HSN and lean the LSN.

the HSN will not cause it to flood at idle. the LSN is very rich and HSN is very very lean.

your engine in the video like others and myself said, is rich on bottom and very lean on top.
three things again, Richen HSN and raise idle since its "flooding" and then lean lsn. and after that will require lowering the idle back down because you've Leaned the LSN
the LSN controls the stationary idle and the LSN is what determines if it loads up or not in conjunction with high idle speed.
if you dont wish to take the advice and get your engine running properly i suggest running electric or having someone physically come and make the above adjustments for you.

)Start your engine and get it to idle.
)With your tuning screwdriver ready, pull the throttle wide open and start to unscrew the high speed needle (brass fitting) until it starts to sound right.
)Next, start tuning your low speed needle (carb slide) until you get a steady idle.
From there you should be able to fine tune your engine.

I know it's tuning 101, but just in case... the brass fitting is the high speed needle and the one on the slide is the low speed. It almost sounds like your richining the low speed.

also the factory settings is a base setup to allow the engine to start at least, you then tune from there.

I chased my tail with a Traxxas 3.3 (different engine I know) for a long time. I bought the truck/engine new. Could never get the tuning right. Went from lean to rich to lean/etc without changing the tune. Compression was fine. Replaced the carburetor and bearings, tried sealing it up, new fuel lines, tuned until I couldn’t take it anymore. Threw in the towel and put in a used OS based engine that I got with a truggy that I bought and it has been great. Doesn’t hurt to try and fix it but sometimes you just get a lemon I think.

Unless you've now got different issues to the video you posted you...do the above. i've seen it so many times before, please just do the above.
if i took any of my cars outside right now and filmed me making the HSN silly lean and LSN super rich it would do exactly the same as the video.

Again, richen HSN and lean the LSN, maybe you need to find a hobbyshop that can turn that HSN screw counter clockwise and the LSN clockwise.
