Might try spray white lithium grease down the cable or run oil down it... the tend to wear and become inaccurate...

On engine swaps one of the biggest mistakes is using the wrong flywheel. People will find that an 8 pole stator doesn't work. They then switch it back to the 6 pole. But in 99% of the time they will use the bright shiny new 8 pole flywheel. WRONG.. you must use the OLD flywheel AND the OLD 6 pole stator...on the new engine...
The second problem is.... it still doesn't work!!!!
Attempting to hook -up and use the new 8 pole stator on the old rectifier /regulator probably fried it...
Live and learn...now you need a new 6 pole rectifier regulator.
or.....
put the new 8 pole stator and flywheel back on the engine and buy a new 8 pole matching rectifier/regulator...
Yeah complicated...

Rich is right.. you should have about 12+ volts AC on the yellow wire and the white wire and ground. It is important that the plug be disconnected from the R/R or you will get weird readings... Attachments:

OK the hiss is different than I first thought. I suspect you have flooded the engine and that is why it won't start. Remove the spark plug and see if it is wet...
If the plug looks wet then leave it out of the engine for a few hours...so the engine dries out and the gas evaporates.. then replace the plug and try to knick-start it...
I honestly don't know what the sound is...hopefully Alley or others will know

You need to check the hub at the wheel and make certain the cable is fully screwed into the speedometer in the dash...
There are a couple of different types of cable... you have the wrong one.. check your new one with the old one

Disabling the alarms on many brands of scooters requires a bridging of the wiring harness...you can't just pull the fuse. Perhaps you can in yours but in most you can't do this...

Alarms on these scooter are CRAP... they are a very common cause of all kinds or weird running engines and electrical problems. They also drain your battery overnight.
If you like walking home 20 miles ... sure hook it up and use it... I can just about guarantee that sometime the alarm will fail and you won't be able to start the scooter.... It is a very common problem...
Its up to you...

They are easier to get a straight stem but you can do it in a 90 degree...lean the scooter over on a 45deg angle and use a engraver vibrator... The other alternative I have used is to break the bead on the tire with a C-clamp, pour in the beads and re inflate with a compressor... www.innovativebalancing.com/service.htm

Alarms do little on scooters and any thief worth a damn can defeat them and start the scooter in seconds... better to use a rotor lock or GPS tracker... if you are really concerned...

Well if it sat for longer than a couple of months the carb is probably plugged and the jets need to be cleaned...
Check the green ground wire that runs from the engine to the frame...hold the spark plug against the valve cover metal and then also try it a clean part of the metal frame.... if it sparks on the frame then you know the engine ground is bad...
Check all the connections to the plug boot and the ignition coil...
Sounds like you have a number of problems.. probably electrical and fuel...need to address them one at a time...

I have seen ACV ECUs but they usually have their own rectifiers, so they actually run on DC.
I would think all the ones on scooters are DC... as Rich mentioned

You need to buy yourself a multimeter... they are like $15. Then you need to check the voltage across a fully charged battery with the scooter running at about 1/3 throttle...
With the meter set at VOLTS DC you should get a reading of about 13.5 VOLTS. If it is less than 13 volts the battery is not getting charged properly... and other things need to need looked at...

Sounds to me like the battery isn't getting fully charged by the scooter electrical system or it is getting drained by something.
When you run it for a bit the battery comes up to full charge and it starts again...
The hissing is just the compression escaping from the valves... Check your plug to make certain it is tight and not hissing from there.
