Alex,<div><br></div><div>We* found that the Lister had to be significantly advanced when running on woodgas in spark ignition mode.</div><div><br></div><div>It was anticipated that we might have to be 20 degrees BTDC, but when the engine was finally running well, it was found to be around 57 degrees BTDC. </div>
<div><br></div><div>The Lister has a 24" diameter flywheel, thus a 75.4" circumference. Our optimum ignition point was found to be 12" on the rim ahead of the TDC position.</div><div><br></div><div>The Lister rpm was limited to 600rpm because of an undesirable resonance around 610rpm - a quirk of the specific engine we were using at APL. Normally the 6hp Lister should rev to 650rpm without vibration.</div>
