Engine has no compression... Please help
#19
Ok, I got the engine pulled this morning (didn't have time to get the clutch or flywheel off though) before going to work. I can now see in through where the pipe attaches and see that the piston move up to the point where it gets snugh, but no further. I am spinning the flywheel so to see this.
So, what would cause me to still be spinning the flywheel but the piston appears to stick once it gets even the slightest of resistance? I plan to take the back plate off when I get home to see if I can see anything else, but I am starting to think it may not be a issue with the piston sleeve, but more like somethink broke or came loose inside the engine.
Thanks again for everyones help.

loose flywheel nut. its not smashing the flywheel against the collet so when the piston hits the top of the pinch the crank stops and the flywheel spins

THANKS TO EVERYONE... I got it torn apart tonight, cleaned it up from the fuel leak and put it back together and it is working as expected again. While frustrating in the begining this was a good learning opportuity for me since I am still new to this.
This is a great forum and everyone is very helpful. Thanks again for everyones help.

With plug out and you feel it spin free isn't bad that means theres no pinch. You know a engine is broke in when no pinch is left, check compression. Put in plug and turn if still very esy to turn i would say buy a better engine like werks. Not really worth pinching since its a rtr rngine and you can get werks engines for $200. Also if it was linking and the needle wasnt loose tighten the gold outsert by the nut at bottom of gold. Also seal the engine with sealent on carb, backplate.
