Alvis Leonides aero engine

[TheOverbank]

Hi Uwe, not much in the way of big radials around, you could try "craigslist", they sometimes have interesting bits and pieces - they had a V12 Allison the other week. Pity about the propeller, I really need one. Hope you get your engine sorted,  regards, Kev.

Hi.

I have a question to you.

I`m owning an Alvis Leonides 503/7A 9 cyl.

and now want make it starting.

Could you remind how much pressure the

gasoline pump need to supply (from the tank

to the injection pump)?

It would be great if you could tell it to me.

Thank you.

Yours, Uwe Wulf

@dwerke Hi Uwe, the engine in the Sycamore helicopter, which is similar, quotes 10 psi for start up, then 23 -27 psi when running. Hope this is useful. I don't suppose you know if the propeller from your engine is still available? I need one for my ground running project.  Best regards, Kev.

@TheOverbank Hi Kev, thanks for your information. I installed a mechanical driven gasoline pump, which comes from russian M14p radial engine. It seems to deliver a little much pressure, but it is possible to reduce the pressure by adjustment. I also have a ground-running project, as you can find in my chanal. But I didn`t bought the propeller. It was offered seperately and was sold for 550 EURO. By the way, does anyone have another kind of radial engine for sale to me, probably a bigger one? Uwe

Thanks for that, the Lion is doing well, hopefully running this year, the Leonides is now sold but the new owner runs it often.
