Professionally restored dual carb BN-7 with about 200 gentle road miles on the clock has become progressively harder to start over the last couple of weeks. Yesterday starter turned over briskly as usual but it took a very long time to catch. Then it sputtered very meekly for a couple of minutes until it finally smoothed out and ran evenly, idling at about 800 rpm as usual. After a careful drive lasting about 20 minutes, finishing with a strong run to the top of the hill to my home, during which the car performed flawlessly with normal oil pressure and operating temp, the engine surprisingly exhibited some brief diesling (for the first time) at shut off. Today the engine just will not fire. The full pump runs as it should until the bowls are full, then stops. A short sputter on the initial push of the starter button . . . . then just cranking after that with no ignition.
There are no apparent problems with connections or signs of fuel leaks, nor have I made any changes in adjustments to timing or carbs.
My sense is that this condition has been developing and today is the tipping point.
Any suggestions as to where I start to troubleshoot?
