The engines will start amazingly rich, so don’t be afraid to try different needle settings, though the recommended 2 to 2.5 turns open worked great for me. Just make sure if you turn the needle all the way in to do so gently. Over tightening can easily ding up the needle.

Take another look at the glowplug. With the glowplug out of the head and in your hand attach the power lead to your battery. I don’t know what type of battery you are using to drive the glow plug, but if it is adjustable feel free to turn it up or down when looking at the plug. When the battery is connected the element should glow yellow, near white hot. Not a dull orange, red, or anything else. Imagine looking at the sun on a clear summer day. That element should look like there is no way on God’s green earth it could withstand those temperatures. If you only have an orange glow, odds are something is wrong with your plug or your battery is too week to drive things hot enough.

For what it is worth,
