Starts only with starter fluid

[hush]

So I have this "free" 2008 Hyosung SB50 Super Cab scooter I was given and so far the bill is $650 way more than the bike is worth really but I like saving old bikes so I keep throwing money at them. So far I have replaced carb with new one from Korea, ignition, reed valves, battery and tires plus stripped it to frame and repainted it. Here is the problem, it will only start with a squirt of ether (starter fluid) and then it runs quite well even idles. I have had the top end apart and removed piston to check rings and bore but both are ok, initially I thought the problem was lack of compression but that does not seem to be the case, I only guessed at that as I figured the lack of compression was preventing the vacuum tap from opening and supplying fuel. Does anyone have a thought on what my issue could be? I have removed the engine 3 times to bench it, cleaned out the carb 8 times just to ensure it wasn't something easy like the slow idle jet blocking.

Is the choke cct actually working? No choke will be very hard to start. It's actually an enricher not a true choke, but semantics.
