火咀 damaged

Hi all,

Any brother can tell me why 火咀 always burned (damaged)
after I started the engine a few times (less than 10 times)?
My engine is hand pull type.  Is it because the big
needle open too much?

thx in advance

For my experence I only know if yr engine internal pressure is too high,
it with easy to cause the glow plug damage.
Or yr high speed needle setting too rich.

thx brother Valklai, I will try to tune my engine to make it not too rich.

壓力太大了,加盤頂介子,教油針好似幫助唔大
