Question about a Dexta Engine troubles

I have also noticed that every so on she will blow out a puff of black smoke, almost a miss fire. Could that be a injector or injector pump problem? I'm hoping not as I had them all overhauled.

I nterserted to hear your comments.

Your misfire problems if related to the earlier Fordson Dexta range could be due to fuel being drawn into the intake manifold via the cold start feed pipe. A small tap is usually fitted to this close to the manifold and should be turned off after use.

If your problem is on the later range some times advancing the pump timing one degree can help cure it.

Ford also fitted "anti flutter valves" to the injection pump where the injector pipes fit. These are a banjo bolt with a high head as opposed to the flat head that were used in early production. they are simple to change and are available from Case New Holland.

Cold starting problems can be cured by installing a cold start unit to the intake manifold near the rubber connection at the front. This can be identified by a pipe and wire at the back of the manifold or just a plug if one is not fitted. the cold start is worked by the ignition key.
