Unhappy Losi 8ight t 454 flywheel spins freely, no compression

Hi all,

I have a brand new Losi 8ight 2.0 t and after carefully breaking it in and having a little fun with it, now the engine doesn't start.

I poked around and I noticed that the flywheel spins absolutely freely, no compression whatsoever. I took the plug out and watched and I can't see the piston moving while I am spinning the flywheel.

I used to get hydralocked while starting the engine the first few times and I'd have to push the flywheel back.

What should I check, what can I do to troubleshoot further?

Tim

sounds like your flywheel came loose. take off clutch bell and tighten your fly wheel and you should be good to go.

For sure your its your clutch nut I would clean the threads with Carb cleaner or cleaner before tightening up again

UPDATE:

You were right it was the clutch nut. What happened is that I took the engine out of the kit and tried the remove the clutch bell but I couldn't hold on to the fly wheel in order to stop the crank from spinning.

So we had to remove the exhaust and stick a ziptie (or some other soft thing) into the chamber in order to stop the piston from moving up and down. Then I could remove the clutch bell and tighten the flywheel. 10 minutes all done and everything is working.

Thanks for your advice.
