Exclamation GXR18 Kyosho DBX will NOT STart

Okay so I bought a DBX and all was good except the pullstart. Engine has compression, servos, work, no cracks in fuel line/tank etc. I converted it to roto to simplify startup as I have a HPI RTR3 Mustang that works fantastically on roto. This SOB will NOT start for anybody or anything. I've taken off the head and the piston rolls smoothly and the fuel flows fine. Carb is open the .3 mm that's suggested as well. The engine flooded just a minute ago so I know it's getting fuel. I've also checked my glow igniter as well as taken out the plug in this engine and verified the entire element lights. I have another plug, but it's a longer one than the one in the DBX and I'm pretty sure that wouldn't work, right? Does anybody have any other ideas? The car doesn't appear to have been bashed around too much as it's got little scratches etc and everything works well except for it not starting... Any advice you can give a newbie would be great. It just seems weird that the engine is turning over great but not starting. I've even taken the engine off the car and the entire assembly spins freely like it should. Granted when in the car the flywheel(the gear at the very end of the shaft?) doesn't spin so it goes nowhere but the engine isn't fully ignited either. Seems strange that heat, compression and a volitle mixture does not result in a boom. Any advice would be highly appreciated as I'd love to get my offroad up and running. Can't really go bashing with my HPI... well for long at least lol.

Perhaps something in the engine is famaged? I didn't want to strip down the internals until I'd covered the other bases. What should I look for as far as damage in there? Bearings? Clutch? etc.

It's in correctly and turns the engine one to one with my roto. Turns in the direction that would turn the wheels forward. When separated from the chassis all parts turn clockwise. Looked at the clutch and it seemed a little worn but I don't think that would cause an entire failure of starting.
