Thunder Tiger Raptors 30-90 - Imperio > Clutch Issues?

I was attempting to start up my Raptor yesterday and accidentally flooded the engine. (ie I knew b/c the starter locked up). After removing the glow plug and clearing the cylinder I tried again. Now it would turn (slowly and with some resistance),however both the main and tail gears attempted to rotate. My first guess was that something was wrong with the clutch so I dropped the engine and checked it. The shoes of the clutch were not "sprung," in fact they still looked new. I also inspected the one way bearing and that appeared ok as well. My question is, "If the clutch liner clearances were fine the day before (and I assume they still are), what is causing the malfunction? Did I warp the start shaft somehow? I'm kindof stumped
In the mean time I went ahead and ordered a brand new clutch, bell, liner, and assorted bearings in hopes of curing this problem. With any luck it will be here by this weekend!
Any positive suggestions are greatly appreciated!

Make sure the nut holding the fan on the crankshaft didn`t spin loose..if it did clean the threads with alcohol and loctite it back on...

Fan Nut

I thought the same thing... and it DID slightly back-off from the fan. However when the whole assembly was put back together, the problem persisted. The only way that I can really describe it is to say that when you spin the start shaft, it isn't smooth. The engine turns over with it's normal plop from the compression but there's also a rough/raspy sort of sound coming from the clutch area.

My second thought would be..is the start shaft pushed up from the bottom far enough that the clutch bell isnt rubbing on the top..it can be a PITA to hold it up tight and get the start shaft coupler tightened down. if thats up all the way I`m not sure what else it could be. You may want to put a drop or 2 of tri-flow ( or similar lube ) on the one way bearing.

That would explain the clutch lock-up as well as the weird sound. I'll look at the bottome of the clutch bell for any signs on wear. THANKS!!!
