Well today was the day. After much frustration with the Saito 170R3 (now I remember why I haven't used it for several years), I got some air under the Waco's wings. The 170 has far more power than the model needs, even when it dropped a cylinder, power was more than enough. Even though I'm using a Sonic-Tronic's on-board glow, the engine kept dropping the cylinder that's at the 7 o'clock position (looking at it from the front). I'm using a 4-cell 4500 Nimh and it's not giving out enough amps to keep the plugs hot enough. Does anybody have any suggestions on how to keep all 3 cylinders lit?
Here's some pics.

I have been using these for many years now. I have never had a problem with the battery life as it only comes on if the plug starts to cool. Never lost an engine when using this device. You would need a single cylinder model and a twin cylinder model. While I have never had a 3 cylinder engine I have used both the one and two cylinder units and both worked as claimed.
