You can run it as is if you want. Im sure you will have not trouble.

Startings is easy. Start off (initially) with the needle about 4.5 turns out. Get the engine a bit "Wet" first by choking ... put your finger over the muffler outlet, and spin with the starter. Then remove your finger, and spin it again a bit. Hook up your glow....use the starter - it will fire nearly instantly. Let it run there for 10 seconds. Turn the needle in for peak rpm (briefly), then quickly back off 800. Launch the aircraft.

After that, simply back the needle out 1/2 half turn from where it last ran. start the engine. Wait about 20 seconds, then turn the needle back in the 1/2 turn where it was

If you set up the engine properly, the fuel system is ok (and you do NOT fly it out of fuel..shut it down on time), and you do not get a lean run, the plugs will last quite a while. My practice Q-500 has had the same plug in it for 40 flights.

Perf Spec, Dub, or Darrol can supply you with plugs. They cost about the same as regular plugs. Order the HD type.

You can purchase the 2-needle r/c carb if you desire. All of the current carbs feature the remote needle arrangment. Just drop Dub a note for the current pricing. [email protected]

The conventional plug head button is available too - this must be fitted to the sleeve, so it would be best returned for service to make that change. However, even a good K&B-HD or Merlin plug will not last nearly as long as a Nelson plug in the 428 engine. That's the reason we do not use them. Its worth keeping the Nelson style plugs.
