dumped eveoltion .46 in the soil today, now has a tight spot
 

Evolution .46 nosed into the ground at about 65 MPH. Didnt go straight in just skimmed runway. When the piston is TDC it has a tight spot in the rotation.

I removed the glow plug and side cover, everythings looks ok. Havnt taken the crank out yet tho. :(

Anyideas?

thanks in advance

The engine had a tight spot at the top when new. Maybe you didn't notice it?

I nosed mine in from about 70 feet, full throttle. Disassemble, clean & oil. Same hard spot, ran it anyways. Runs great with no issues.[8D]
