2006 500 Auto Timing question

I am checking the timing on my '06 500 and it looks to be out of time and if I'm reading the manual right at Top dead center, the marks on the cam should be parallel with the top of the head and the "A" should be down. Before I start adjusting the timing I thought I would get a 2nd opinion.

I have attached 2 pics one with the mark on the magneto lined up with the notch on the engine case and the other of the cam postion at that point. Tell me what you think

You can't adjust timing. That timing mark can line up on the exhaust tdc or intake tdc. You want to be on intake tdc and at that point you can adjust your valve lash.

I should have worded that differently instead of saying "adjust the timing" I should have said, "set the cam timing" because I'm suspecting it jumped time. I'm trying to verify if the cam is in the correct position at TDC. If not, what is the correct position.

Well first off you didn't have to remove the left side case. There's a allen head plug on the left side case right below the exhaust pipe you remove and align the mark on the flywheel to the mark on the case. Second are you on the compression stroke? But yes, the when the TDC mark on the flywheel is aligned the two marks on the camshaft should be aligned with the top of the cylinder head or pretty Damn close. When I rebuilt my 500's top end I remember my cam marks weren't totally flush with the head but they were very close. Mine runs perfectly. Why are you thinking it jumped? If it did I would replace the chain and the tensioner along with the guides if they are worn.

I had replaced the stator prior to this and put the case back on just to test it before sealing it back up, so it needed to come back off anyway, but i do know about the inspection plug.
The reason I think it may have jumped time is when I was trying to start it, after fixing my "no spark" issue, it wouldn't fire up and I was getting back pressure through the carb, which enough pressure to blow the fuel pump in half. Looking at the marks on the cam and the mark on the flywheel at TDC, they don't seem like they're lining up like they're supposed to. Doesn't seem like there is excessive slack in the chain, but if it did jump time then I'll be replacing chain, guides and tensioner.
Not sure if its on compression stroke or not, but I know no matter which turn I'm on on the flywheel the cam doesn't seem lined up with the top of the head.
What is your opinion?

Thanks for you input!
