I bought this bike not running . It had carb. problem's I put a new one on it and it started up and ran great. Now it just depends on if it wants to start or not. Some times you choke it kick 3 times and it starts then the next time you might kick the thing twenty times before it will start. I got tired of this so I pulled the fly wheel to check the timing . The marks are not even right When I pull the plug and put it on top dead center on the compression stroke the key way is at 12 o clock that puts the hole at 7 o clock on the flywheel the factory mark at 9 o clock and the stator hole is at 6 o clock this is not even right by what it is in the book . So what is wrong is it the wrong flywheel'stator or is it in the engine and I check it a few times to to make sure. I don't even know how it started when it did I know this is not right. ANY IDEAS or if any body has a picture of a flywheel or a stator for a 400fe to see if these are the right parts for this bike its hard to get help around here. If you say Husaberg they run

Hi and welcome
This is an old issue
Are you finding the TDC with precision ? If you have a strobe light use it, make a mark on the flywheel with a pen at TDC align with the mark of the engine case and try 6º deg of advance at idle speed.
If you don't try this

Here is also the manual pag

Thanks for the information and the pictures they were a lot of help. What i found was the key way is just wore out on the flywheel and the crank and when you get it in time and run it hard the flywheel moves on the crank and the timing gets off about 15 degrees.So I will find a bigger key that will center the flywheel to keep it in time. Again thanks for your help. Mrfixit

back in cottonwood, az
of the two pdf files that zaga provided, the second is more accurate for the 400. the flywheel hole and the stator slot will be at 6 o'clock at tdc.
as far as the crank key is concerned, the key just locates the flywheel. the taper on the flywheel and the crank must be almost perfect (never spun before) in order for the flywheel to remain in place on the crank. look closely at the outside taper on the crank and the inside taper of the flywhhel. if there is evidence of scoring from a spin, it will be nearly impossible to keep it from destroying keys in the future.
