RE: OS 61 FX - Won't run without Glow Igniter
Good advice.
Here's another thing to be aware of. Sometimes, fuel can get old and not want to burn. It will be difficult to start and keep the engine running with fuel that has turned bad.
If you can't adjust the engine to run, don't wait too long to try a fresh source of good fuel.
Then, if the earlier advice doesn't fix it, and the new fuel doesn't fix it, be looking for a source of extra friction (like seize marks on the piston / liner.)
Good luck,
