Default RE: Pullstart Not Cranking over engine.

ORIGINAL: UmDaMan

Hi, I have a Force Models 3.5 Engine. The engine is very new, maybe 3-4 tanks of fuel used. It is on an Art Attack snowmobile. I went to pullstart it, and it just pulls freely, doesn't crank over the engine. I know the one way bearing is working correctly becuase I took the pullstart apart and I can see it spinning the axle that its on. (It's grabbing very good) I have taken some photos. They can be viewed here:

I have no idea how this thing is suppose to work. It almost looks like there should be a pin sticking out that the round piece would grab onto to crank the piston... Anyone have any ideas of what is wrong here?


Thanks!
From the middle picture, it looks like the outer part of the crankpin is broke off. Its hard to tell from the pictures for sure, but it looks like the starter pin is broke off.

Did you break the engine in or have you ran it prior to this or did you get the engine in the present condition and haven't ran it yet?
