He sealed the muffler with RTV, my (and others) guess is its getting sucked into the combustion chamber and snuffing the plug.
My offer stands, send me the motor, it will save you a lot of typing
No only 4
Update: It's finally working!
What I did...three things actually:
1) Blew through the muffler pressure release nipple to ensure it was clear
2) Replaced glow plug...once again.
3) Tried new batch of fuel.
So...not sure exactly which was the culprit....but I suspect the glow plug! The new engine I got I never replaced that plug because it was glowing fine. But since it was having problems even starting lately, I replaced it with an OS 8. It's possible it was the fuel since I had been using the same last bit from a gallon...I'd keep draining it and putting it back into the bottle...then back into heli etc. Lastly I guess it could have been a clogged pressure fitting on the muffler but hard to tell....I didn't have resistance when I blew through it.
But it's back! Thanks everyone for the ideas and help!
