273 won't start regularly
Hey good one warwagons! I never thought to check the coil,but I too had a cracked coil that sometimes would not allow a start. Eventually it failed entirely.
You can dry the plugs off with a propane torch. Just dont hold them whilst you do this.:angryfir:
Looks like your engine is running rich judging from the nice fluffy carbon deposits. Could be from a weak coil as well,as the engine may not be getting a hot enough spark to completely ignite the mix.
