Hi, as I know that if we run the engine too lean and this will cause the glow plug 'damage' more fast, how about if we run too rich?? Normally with bodyshell, the temp should go to how high?? max 120 degree C??
That day i try to change OS#8 to Nova#6 plug, I need to increase
the ideling needle, is this normal?? It can ideling for around 10 second than die but for OS#8, it can ideling for wthw whole tank. If the engine can't start, what should we check first, second and etc.

Thanks.
