I went bashing with my ravager roday, doing the 11th tank, not tuned yet, all was fine. Wanted to start the 12th tank, but the engine just wouldn't start. Here are the tests I did:

glow plug is fine
glow ignitor is fine
yes it is primed
yes the flywheel spins when I pull the pullstart
no it wasnt overheated because I tried 2 hours later, still wouldn't start
yes i gave it a little throttle

The receiver battery was dying however, because the failsafe told me so. So what could be the problem?

may be flouded. Take out the glow plug and turn it over a few times while the car is upside down, this will grain the fuel out. Also try changing the glowplug, it may have came disconnected deep inside the plug. If that doesn't work just play with the high speed needle a bit richening it a leaning it from it current position, it may have way too much or too little fuel to even start.

I didn't change the needles, and it started with 2 pulls the tank before. And it's not flooded. And I am starting to panick now because when I turn the flywheel, It's a bit easier to turn and there is a click at a point where I turn it. A CLICK DAMMIT!!!!

any help? I have no idea whats wrong and what to do now.

You must dismantle your engine to check internal parts! TAKE CARE of the way parts are assemble

Good luck!

Are you sure your one way bearing is grabbing the shaft?

Are your clutch springs worn , if so they will constantly grab the clutchbell only allowing it to start with throttle applied. good luck

clutch springs? could that be the thing making the clicking noise? eh, I'll get my friend to disassemble it for me, I'm scared to do it myself. Thanks for the ideas.
