Default Ignition/battery question

A small upright 2-stroke followed me home from's a Caron Bros engine, canadian built, tank cooled. It has a high tension ignition with points, coil, and consensor. It was running at Coolsprings, but when I got it home, I couldn't get any spark, so I replaced the extension cord and speaker wire that made up the ignition system with new 10ga copper wire, and the carbon core spark plug wire with conventional copper-cored wire. I was able to get a spark out of it, and ran it briefly, but then I couldn't start it later. My question is this - I'm using a rechargable 12V battery from a cordless drill for power (I think it's ni-cad), but it seems to go dead very quickly. Do I need to get a motorcycle or car battery, or is there something wrong with the ignition? It's probably that the battery isn't strong enough, but then again, I've used this same battery to run a buzz coil, and it's run for the whole day with not problems. This is kind of new to me, so any help would be appreciated.

I would think your battery should work? Are you using a buzz coil or is it as you said?If its as you described you need a buzz coil.BobRR

I don't see any reason your cordless drill battery shouldn't run your engine for a reasonable amount of time if it's in good shape and fully charged.

I'm not familiar with the engine you've got but, if the points are closed most of the time and only open to fire the coil, that could make your battery discharge pretty fast -AND- the coil would quickly get warm to the touch.

Take care - Elden
