RE: Need help starting a new engine
If you have a good glow plug, good fuel, and good compression, the engine will run. If it won't fire at all, then it's either too dry of fuel, or very flooded.
To start the engine, you must first make sure it's dry of fuel. If you've been trying to start it, and it won't fire, then close the needle valve and then remove the glow plug. Put a rag over the glow plug hole and spin the engine over. The rag prevents any fuel from spitting up into your face. After doing this a bit, replace the glow plug, attach the starting battery, and turn the engine over. It should fire, but not keep running. Now, open the needle to recommended starting point and spin the engine. It should fire up and continue to run. You may have to pulse the throttle a bit because new engines don't have their settings found, and you'll have to adjust the high-speed and idle needles once the enigne's up and running.
