Information on vintage spark ignition aero engine needed.
« on: March 16, 2023, 03:35:25 AM »
I was given this engine some years ago after it had been found in an old shed under a pile of junk & was caked in masses of grime.
It has been disassembled, cleaned & has new gaskets. I have no idea of the manufacturer, only that it has "New Era" engraved on the transfer port cover.
As I have no knowledge of these little engines, I have a couple of questions.
1. What would the ignition timing setting be to start this type of engine.
2. What is the best type of fuel to use? Conventional 2 stroke, (if so what would the petrol/oil ratio be), or is there a better fuel available?
I have an ignition system in a box that will be connected to the engine that will supply plenty of spark.
Thanks for any help in advance.
Regards,
Don.

Congratulations with a nice 'new and shining' Engine  :ThumbsUp:

A rather longwinded explanation about all details about running a Sparkie can be found here :

https://adriansmodelaeroengines.com/catalog/main.php?cat_id=182

There is a good chance that you can find the Engine and it's story on that site too ....

Per          :cheers:

You need a coil, a battery and a capacitor, as the engine already have a contact breaker and a spark plug.
I did 4 of vintage 2 stroke sparkies... the spark should occur near the TDC, and the contact breaker normally can rotate with friction to tune the ignition while the engine is running.
Much fun to run them!

The HT coils are easy to find on ebay, as new copies of the old moped coil, the battery is a plain 4.5 V one , the capacitor is a 0.1 or 0.2 microF 400 V .
this is the kind of coil that works, for moped with contact breaker, not the more recent one for cdi ignition.

the fuel is just plain gasoline with up to 20% motor oil
and the connections :

That's all.

But you may prefer a more recent setup with electronics, such an Rxcel module, but you have to change the contact breaker for a disk with a magnet for the Hall sensor trigger...

Thank you Admiral_dk & Zephyrin for your input into my request for information.
I have read the information on the mysteries of the "Sparky" engine form Adrians Model Aero Engines. Once I have the fuel & correct oil grade, hopefully & can get it running.
Thanks again.
Regard,
Don.
