Chainsaws have more compression and this changes the timming and tuning of the engine.
Perhaps you could lower the compression by adjusting the glow adapters depth into the cylinder.
Funny, that actually increasing compression on Poulan 25 (weede) improved things on glow plug. Calculated (not measured) compression of my engine is about 10:1 (after mod) and the engine runs better than before. Also starts easier by hand.

Is your 25 weede a chainsaw or a string trimmer
