Hi,

if a new OS # 8 doesn't work, try an Enya #4 glow plug. Usually this helps.

And / or, leave the glow starter on and make the engine work to break it in.
If that isn't possible, dismantle the engine and use a paper towel to clean the sides of the piston, that is, rub away the brown residue that has formed.
The problem is quite common with OS .5x engines that aren't broken in properly, but only hovered.
