Getting a new engine to start can sometime be an art. GET SOME HELP! Surely there must be a club nearby. Each engine has its own quirks, and depending on a number of factors, that first start can be troublesome. You don't tell us what prop, glow plug, or fuel your using, which would be good information to help us give you advice.

When I'm starting a new engine, I start with the needle valve about 3 turns open from fully closed. This seems to be a fairly safe location. I then prime the engine (throttle fully open, finger over the carb, and turn the engine by hand 3-5 times). Then I close the throttle, and with the glow igniter OFF, I flip the prop a few more times until I feel the engine loosen up a little. Now I know I'm not hydrolocked, so I install the glow igniter, then start flipping. If the engine doesn't kick in about 10 or so flips, I lean the high speed needle a few clicks, reprime, and try again. I continue this process until the engine kicks over and starts. Once it starts, I leave the glow igniter installed, and try to throttle up slowly. If the engine gets to full throttle, I move behind the plane, and adjust the high speed needle for peak RPM, then richen it about 1/4 to 1/2 turn, and remove the glow igniter. I then give it about 1 minute at full throttle, then shut it down.

After the engine has fully cooled, I refuel it, and restart it. I then run a full tank of fuel through it on the ground, varying the throttle setting from idle to full throttle, with full throttle runs lasting 30 seconds to 1 minute, frequently checking the quality of the exhaust stream (white smoke, no metal particles, clear oil), and listening for any transition problems between idle and full throttle. When that tank of fuel is gone, let it cool down.

Now refuel it, restart it, set the high speed needle to about 500 rpm below the peak (to the rich side) and fly that sucker. If this is your first plane, get an instructor. Otherwise, the first flight will be pretty short.

Good Luck!
