Keep changing parts until you find the solution! No, just kidding. Many will do this if they don't understand how an engine works. It sounds like it may be a hung choke. Engines need extra fuel when cold, and die when warm if they are still getting that extra fuel. Also, low oil level will give the same indication. There are many variables.

I have a 139qmb 50cc scooter runs great when I first Rev it then when I let off the gas and go to Rev it again it revs a little and misfires and dies. Carbs fine cdi fine new plug could it be the coil. ...

Check your vacuum lines and fuel lines/filter,another possibility is the manifold between the carb and head. If there are any splits in any of these you will get rough idling and stalling! Safer to replace the cheap factory ones with upgraded parts.

Fuel Problem

If you have 2 carbs that work on another unit but not this one then that narrows down the fuel problem to either an intake/ vacuum leak or bad fuel in the tank.
The compression sounds a tad high which could indicate valve timing ( exhaust opening late or not long enough)
On the ignition side you could have a bad CDI , weak pulser coil or sheared flywheel key.
I believe I would lean toward suspecting the ignition. I had a Honda that gave me fits acting like a lean issue. I was in that carb 25 times if I was in it once. Same thing, idled fine but died on acceleration. It was the CDI. Put a spark tester inline with your spark plug and see if the unit dies due to lack of spark.

Retro scooter cutting out and not starting

did you check the sparkplug? is the primary coil is good and still can deliver power?Your ignition coil is good?if all your answer is YES",then its time to check your CDI...
it is 99% the problem is in CDI..Replaced it..,But when your motorcycle is contact point operarted,then check the "timing",if you sure you set the right timing but it is still not firing,then replace the condenser.
You may also get rid to your ignition switch because sometimes there is the problem due to the stucked up of its component inside it at is grounded continously even the key has already turn into "on"mode.

Only 750 miles on scooter. Put away with stabilizer. Starts bar-o-o-m like it's going to run fine. Then stops and won't start. Checked plug and spark. Plugged line?

The stabilizer is a bad thing for some carbs. It has a chemical in it that can eat away seals and gaskets inside your carb. Grab a gasket set for it, replace those, make sure to spray the carb out, then put it all back together adn you should be ok.
