Whoops, sorry Russ, my opening should have read "Indeed, Russ, Jan Ridder's work is fascinating ..."

--- Quote from: geoff_p on July 21, 2012, 06:42:57 AM ---Indeed, Jason, Jan Ridder's work is fascinating - I spent most of an evening reading his page on ignition systems.
I had actually incorporated a piezo-ignition from a cigarette-lighter but found, quite independently of Jan, that the force required to 'squeeze' it is considerable. Of course, this is happening during the compression stroke so the poor old flywheel has to supply a lot of energy.
Anyway, as mentioned earlier, I'm going the CDI route: the system I ordered from HobbyKing has arrived and installation has begun.
Thanks for all your help and ideas,
Geoff

Geoff, as Russ says, Jan Ridders has added to his spark ignition page very recently. having found a small lighter circuit which isn't piezo, so no squeezing is involved. Too late now, I suppose.

I'm pretty sure that is the page I read (and saved-off for reference) but thanks anyway.
Foolishly, today I decided to re-thread my cylinder head for M10x1 for the CM 6 spark-plug - it had been M6 to suit my home-made plug.
Being unwilling to go to town to buy a 9mm drill (M10 tapping-size) I fiddled and faffed around and have ruined the cylinder head.
So tomorrow I'll just have to cast a new one, drat it!

hi geoff p sos for the delay in the replay im gowing off a 125 singel silender engine right on the honder ther is a altanator with a flywheel on the out side of the fly wheel ther is a rased spot this is magnetised on the inside of the altanater hawsing ther is mawnted a triger coil as the magnet passes this coil it preduses a smale voltige thes then gose to the coil the electronics in the coil amplefiy the signel and produses a sparke
