Hello
I have a Nuffield 4DM, that i have recently purchased, and it seems like its had a series of bodges done to it over the years, and very little work mechanically, resulting in lots of wear. I am slowly going through it, I have done the brakes, unseized lots of linkages, rebuilt the hydraulic system, worked on the wiring, put a new exhaust manifold on, lots of other new bits, and I have recently started overhauling the steering.
Anyway, my question, it will not start on its own. I have made a thermostart system, simmilar to the Perkins system, which i guess will help, as she will start fine with a little warmth from a blow torch or a hot air gun.
Now i have a Simms pump, and i have a cold start, excess fuel button. On our David Brown, if its cold weather she will not start at times, so i put the excess fuel 9n and what a difference, fires straight up. When i activate it on the nuffield, it makes absolouteley no change what so ever. I find this slightly odd, what do people think?
I have a compression tester, which i plan to use at the weekend, but any other advice on what could be happening would be greatly apriciated.
I have thought of doing work on the engine, but i have to limit what i am spending on the tractor as i have orther projects too.
Thanks in advance
David
