Has anyone tried this bleeding method: spraying diesel into the air intake?

Please: can we stick to bleeding fuel problems, rather than petty squabbles about how someone chooses to express themself?

May I ask why you chose it reply to my one single post rather than reply to the previous three posts?
I was merely pointing out that the guy moaning about the guy saying much the same three times in a row (but inmportantly not exactly the same) had not read the replies correclty, and had replied half cock as it were.

As for the bleeding idea, I have never come across this idea before, and have been servicing diesels for over 30 years now,I kind of think the diesel will just lay in the inlet trunking and not get sucked in with the incoming air as there simply is not enough air movement.
 
Old Listers had an oil injection plunger on top of the manifold, I presume for lube and initial firing. We used burning paper under the air inlet to start an old Baudouin 3 cyl 'ticketypop' boat engine. A gas torch is safer and easier

Our old 30 foot gaff cutter had a lovely 4 cylinder air-cooled Lister.

If I remember rightly, each cylinder had a little oil bath which you topped up just before a cold start (or was that the Sabb in the H27?).

Our old Halcyon 27 had a wonderful single cylinder Sabb: it must have inherited some of its genes from that wondrous beauty!

Oddly, I was doing research into what a semidiesel was and found that Sabb manufactured them for fishing boats before they moved to diesels. My dad had a Halcyon 27, and the Sabb diesel was very comforting - an engine you felt would go on no matter what, at revs where you could count every power stroke! Diesels are vastly more efficient, though around 12% for a semidiesel, around 50% for a diesel.

1) A simple matter of cumulative impact: my request was to everyone, not specifically targeted at you. Apologies that I hadn't made that more obvious. Let love, peace and harmony prevail (man!). ✌

2) Your point about the diesel 'mist' just lying in that long inlet trunking was just one of several things that made me want to seek out the knowledgeable opinions from this august forum about that oh so simple looking solution. Thank you!

Wasn't it those Sabbs that had starting 'cigarettes' for seriously cold, mid-winter, starts?

As you say, a very comforting, reassuring, slow, steady, pulse, that shook the rigging.

(thread drift: I loved the reversing prop on the H27, too)
 
Maybe a bit late to the fun here but. I had a Merc OM636 that was a pig to get primed and running once out of fuel.

I poured a small amount of diesel down the inlet manifold and it fired to up for a few seconds, and by heck it ran well enough to get it running again.

1973 I was in a boat with a Lister SR4, 36hp, air cooled, in the wheelhouse with us, and I still have the tinnitus.
 
I've never done it, but I've heard good results can be had bleeding a diesel engine, by pressurising the fuel tank, nothing crazy, just enough to push it along the fuel pump.

Made sense to me, what do the experts think?

You'd have to block of the fuel return line

Cover the breather and as you say slightly pressurise the tank, with the bleed screws open and it will work like a charm.

Of course a day tank above the engine makes this all a lot easier!
