Sabb 10 HP starting

[duncan99210]

Bedford MK 4 tonne trucks (the workhorse of the army for of so many years) all had easystart pumps in the cab. They were for cold starting: you removed the top of the container, put an ether capsule in and replaced the lid. There was a plunger you pushed down to break the seal on the capsule and a small pump which was used to pump the ether into the inlet manifold. Pause a second and crank the engine. However, it was aimed at sub zero starting and the capsules only issued in winter when the weather got cold enough to warrant their use. So ether is a solution which works and used to be designed into engines of the same vintage as the Saab but thinking seems to have changed over the years.

Danke schoen, Duncan.

My engineering thinking is firmly rooted in the 1960's.

However, back to the OP, as long as the next ice age does not start overnight, get some oil around the rings check you have fuel and spin her up, she will run easily. If not, cylinder head off, new piston rings and hone the cylinder. Simples.

Thankfully no two engineers will agree on anything ..... life would be boring otherwise.

I'll just copy and paste from the first website I found:

Even up to 1990 the Leyland Freighters had an Ether starting system as standard which involved a small reservoir of ether that was pumped into the inlet manifold by means of a hand pump in the cab.

We had 1993 Seddon Atkinsons with Cummins L10s that had the start pilot ether injector system..Leylands...aecs..was almost std fiting years ago.

I had an '84 Cargo Horse Lorry with an 'Easystart' reservoir of sorts on it but I never knew what I was supposed to fill it with so on cold days I just chucked a petrol can cap of petrol down the intake and she fired up with a fine roar.

Lots of trucks had ether start assist on them. IIRK, Cummins didn't have an excess fuel button, hence the bottle of ether.

So did the Transit fitted with the York engine.

At least some diesel engineers agree avec moi. :encouragement:

Was working on a Ford Sabre engine the other day. Ancient technology, good for its day. Interesting, I found out the compression ratio was only 14:1. The engines you are talking about, I suspect similar. Engines today run up to 24:1. My MD22, ancient in terms of development, is around 17:1. The point I am making? You carry on using Ether based starting aids, they were designed for low compression donks, designed in the WW2 era. If you need to use it nowadays you run the risk of damaging the engine. I have personally repaired engines where the use of it has caused pre ignition, as Vic says, you have no control over the ignition point. The typical damage caused is broken rings and/or squeezed piston ring lands causing the rings to sieze.
The reason people say engines get addicted is that the use is self promulgating, the more you use the worse it gets. Its only use nowadays imho should be as a last gasp get you home measure with the knowledge that it could be making an existing problem worse!

I like that Quimby I was thinking on that line. There is a lot of speculating by me here ,I am a it might not start in the cold type ,more than a it`s cold and the boat engine did not start so I have a fish and chips and just fix things . There`s no guarantee's in life but I like to cover it . Yes it cranked is thread has given me a good insight into how to start it easier . Quimby has definitely got something to make a big difference to it efficiency . I await the next trip to the mooring over the tide by hand start and look at the heater plug option
Thank you

JC, if you give a s**t about reliably starting your engine, cigarettes OR glow plug conversion are not the answer.

Good luck with your new boat and that tide.

I'm out of here.
