Hi all,

Car is 1984 W126 380SE

The car isn't used regularly, for a year or so it never had hard starting problems, but 2 weeks ago the engine failed to start, and finally started after many tries. However last week it refused to start no matter how many tries, after sitting for a week or so.

Put few drops of gas into the air intake flap at the air filter, and it started fine, and runs fine, no more starting problems so far as it was driven for 3 days in a row.

My question is, is this a common thing for older vehicles??

If so, what's reason behind it?

Or could there be any hidden mechanical/electrical/fuel-supply problems?

As far as I know the engine normally starts find cold or hot, and no known engine problems other then misfire in 1 or more cylinders at idle about 50% of the time.

Thanks for your help.
