Had 'em on the old fordson majors, you'd never get 'em started without in
cold weather.

avoid the latter if you can ('s not always possible) since it's not good for
the engine. You can tell this by the god-awful clatter it makes.

If you do use it, apply to the intake in brief short squirts while cranking,
just enough to get it to fire. overdoing it really does hammer the engine.

My old one is from the flower power era! I think the newest is 1975
and it was cold on it today.

Agreed so only in am emergency. As you say over do it and the ether
detonates as a premixed charge, this knocks the ring and piston lands
about, this causes loss of compression and hence more ether is used.
Classic addiction.

The other thing to consider is that if the excess fuel button has been
used and a start failed then there is a lot of fuel in the cylinder. I
always spin the engine over with the stop control out if I think this
has happened.

Mind it doesn't become addicted though!

that's where people go wrong with Easy-start, though, they blast loads of it
into the manifold, crank the engine and it then goes
"CLATTERCLATTERCLATTERCLATTERCLATTERbruummmm". (OWTTE). All that clattering
is your engine being knackered.

best way to use the stuff is to start cranking the engine and then fire off
a small (about half a second) squirt ideally direct into the inlet, but
through the air cleaner will do. If it doesn't catch, try a 1s burst. Use
as little of the stuff as you can get away with and still actually get it
started.

but the best bet is to work out how it's supposed to be started. The
perkins things with the preheater in the manifold require the right
technique - I used to crank the engine for about 5 seconds, then turn the
key to half-cocked which energises the preheater. Wait 'til you hear the
"woomp" of the diesel in the inlet manifold igniting and then crank the
engine, and generally it'll start.

the preheater in the manifold (if it's that type) is fed with diesel from
the injector leak-off pipe, and I used to think that cranking it a bit first
made sure there was some diesel there to supply it.

Whatever you do, do not use a combination of ether and thermostart unit.

hmmm. I imagine that could be exciting.

oh and another "don't do", while we're on the subject...

Easy-start in a hand-cranked engine. Bloody near broke me wrists.

Ahem.....
been there, done that!

Not actually a thermostart, but a fcuk off big glowplug in the inlet
manifold, combined with a poor aim, resulting in loads of easy start all
over the chassis. Was quite spectacular at the time! The sight of a fat
bloke running around the workshop screaming "SOMEBODY GET ME A FIRE
EXTINGUISHER" was quite amusing too! No damage done luckily, seems ether
must burn with a fairly cool flame, there were flames coming off the wiring
loom, pipes etc, but nothing melted..
