1985, 2.3 190E - When left overnight or long periods of inactivity, the
merc struggles to start. It eventually does start and runs fine.
Once running, if shut off and restarted immediately - starts great.
Once running, it shut off and restarted within an hour - starts great.
But leave it shut off for longer, becomes a bugger to get running again.
When the key is turned in the ignition, the engine turns just fine - but
doesnt catch. Have to turn the engine a few times before it gets going.
Once it's running the engine is smooth ie no rough idling or variations
Any suggestions where to start looking?
