Have you tried a new glow plug?I've had a bad plug before and when the switch glo went off the engine died.it's better to ask for forgiveness than for permission

As trek suggests, I would start out by changing the glo plug without doing anything else.... if that fixes the problem then you're done....

If the problem persists, start the motor as usual......then, do the "pinch test"..... that is, with the heli at a nice idle, pinch the fuel line closed with either a clamp or with your fingers and listen to what happens.....

If the motor continues to idle for a few seconds (4-6) and then the motor RPM increases slightly and then the motor shuts off, then that means that the low end mixture setting is correct.....

If, however, you do the pinch test and the motor immediately shuts off then the mixture is too LEAN..... Richen the setting about 1/8 of a turn to richen (usually counterclockwise)and perform the pinch test again....

Repeat until the ideal condition is reached.... that is, after the fuel is pinched off, the motor should continue to idle followed by a slight increase in RPM prior the to motor quitting...

Let us know what you find....

PS-- I have also seen old/contaminated fuel act in a similar fashion... so, if you've had this fuel laying around for a while, borrow a tank of FRESH fuel from a friend and try that prior to doing anything else.....
Been there, done that and old enough to know better.....

Once the motor is running, there is no "electrical" that keeps it going.

You have a bad plug, a carb tuning problem, and possibly a rear bearing falling apart. If you used any form of silicone RTV between your crankcase and muffler, that could be flaking off, finding its way to the plug, and fouling it.

Water in fuel may also be a problem.
