Default RE: Pullstart Not Cranking over engine.

Ithink proptop might be correct it could be stuck in. Yes I did break-in the engine. It's been in storage for several years, so makes sense now that it could be stuck in. Ijust looked at it, and it doesn't appear to be cracked off, it is too smooth looking.If it did crack off, wouldn't their be some severe damage done to the inside of the engine Piston, cylinderetc? Iput some fuel on inside and closed it up, hopefully the pin will come back out, if its stuck in. Tomorrow I will get out my camera with a macro lens and take a nice closeup of that crankpin.


Thanks to all the other posters...

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. Iwent to pullstart it, and it just pulls freely, doesn't crank over the engine. I know theone way bearing is working correctly becuase Itook the pullstart apart and I can see it spinning the axle that its on.(It's grabbing very good) Ihave taken some photos. They can be viewed here:

Ihave 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?
