Saving Old Seagulls

hooked up the frankenstein ignition up to a 40, yanked the cord and she started up and ran on 2 month old 10:1 fuel

she had a bit of a mis-fire, but i think that has to do with the generator coil not being quite strong enough for the particular ignition coil i'm using. had a feeling earlier that might be the case. i'll think that winding a few more turns on the generator coil will smooth things out.

todays success at least shows that the "home-brew generator coil feeding an ignition coil" concept works - so its good to know that i've not been wasting my time (and fingers).

looks like interest in this has sagged a bit so i won't update further. this was a fun project, and its good to know that seagulls don't have become idle if stock villiers coils ever get scarce or prohibitively expensive.

i'll need to add a few more turns on my coil to optimize it, but winding is fairly simple, and auto-style spark coils are cheap and readily available either new or used. i'd encourage anyone to give it a try!

I was getting close to sending you a spare coil....

I had already got a price from DHL.

H-A

well, i do have a couple other seagulls needing coils...

I like this idea Fords here have coil on plug units at a reasonable price for new, Id leave it mounted on the plug.

Hi there,
I have fitted a Bendix Coil from a Light Aircraft Magneto also capacitor from same engine starts runs perfect and fitted with a little grinding of coil poles and removing some of plastic coating surrounding windings(clearance on cam and underside of flywheel) Would not recommend buying new but look around on ebay or aero jumbles for Bendix 20/200 series magnetos or if you want to mount coil remote from under flywheel then look for Bendix 1200 series which will spark a 6mm spark gap with NO capacitor
Hope this helps
ps Don't run with no capacitor/condensor you will burn your points out in no time
