W201 Starting fixed.

[Perseverant]

1990 190e was becoming increasingly difficult to start from stone cold. A new cold start valve seemed to be the answer but I didn't like the price so rootled around in the garage where I knew I had some Bosch bits from a SAAB. Lo and behold, a valve, admittedly with different unions and a different serial number (the first set of numbers was the same) which I dusted off and fitted. Problem solved! Now nearly everything works, even the odometer, and since being busted for speeding I've got the speedometer to read accurately too! Now for the great prop shaft overhaul - got all the bits.
