Hi!
I'm the Swedish MVVS distributor. It seems to me that you do everything right! But don't know the secret to starting an engine. You can of course start any model engine by flipping the prop but a much easier way is to use an electric starter.
It's also important that you use an adequat power supply to light your glowplug. A small 1.2V C-cell battery isn't enought if you are new to engines. The glow plug should glow bright orange or white...not red!
A much better way is to use a 12V, 10-12Ah motorcycle battery to supply power to the glowplug and also power the electric starter and fuel pump. But you must use a glowdriver that reduces voltaget to the glowplug , 12V will otherwise destroy a gloplug. Automatic glowdrivers are readily available at every hobby shop.
It's also vital that you use the correct propeller. For a 7,5cc (.45) engine a 11x6 APC is a good propeller. Do not use a 10x6 prop as it is "to small" if you intend to use the engine in a high winged trainer.

Regards!
