Default Pt19 not starting

I have recently brought a cox PT19 control line plane, but I cannot get the engine to start, I'm sure I'm doing everything right, but it is my first control line plane so there could easily be something I'm doing wrong. Great if you experts could help.
Thanks

Make sure your glow driver is glowing the plug. Should remove the glow plug and physically look at the glow. Should be a glowing orange. Prime the exhaust port with a bit of fuel and it should at least run that prime out. Depending on how long it has set up, there's a good chance the reed is stuck, or possibly even dissolved. If its been sitting for years you will probably need to take it apart and clean the fuel pickup tube, the needle valve, the needle valve hole, and make sure the gasket is good between block and tank/reed plate.

If your flipping by hand they can be hard to start . Prime it by putting some fuel in the exhaust port on top of the piston. Flip it a couple of times . When it sounds like it frying inside the cylinder is the most likely time it wil start and you should try the hardest at that time.

Ok thanks 4 that, it doesn't even have the Reed valve in, so that probably explains it

Will not start without the reed valve in place and a proper seal.

Yes, it should be. Older versions have a copper reed. Newer reeds are plastic.
