How do I align the camshaft and crank gear on briggs stratton xtl 50 for correct valve timing? There is a centre punch mark on a tooth of the crank gear and there is a groove on the cam gear and i have aligned these in both ways possible but this does not work.
Check the air gap between the coil and flywheel. Also the solid state trigger in the flywheel may be faulty.

Yes, there is another reference. You have to watch the cycle of the engine to do it. you should make it so that both valves close just after bottom dead center(compression stroke), and then they should stay closed for a half revolution, then the exhaust valve should open just after bottom dead center again. At the same time, the magnet on the flywheel will pass the coil at top dead center between these two reference points. This way can be slightly exasperating, because you can be off a tooth either way and it won't run right, but will look ok.

Sounds like you will need to clean your carburetor.
Sometimes you can get by with priming it a few times, and letting it
run a few times like that and it will flush the gunk out of the jets,
but most of the time you will need to rebuild the carburetor.
If the mower is over a couple years old, then I also recommend that you
buy and install a new carburetor repair kit, because the diaphragm will
get hard and that will cause it to be hard to crank.
When you clean your carburetor and remove the jet screws, count the
number of turns it takes to seat the jets from their original position.
That way when you go to put the jets back in, you know how many turns
they were in/out.
Please rate me, Thanks
Good Luck, I hope this helped

NO! Do not drill out the rivets. You need to remove the entire blower cover with 4 bolts (2 up front, 2 in back)
I'm going to link you to my two favorite "How-To" videos. Depending on your machine, one of these will show you enough to do it yourself. Once you do one, You'll be a pro. Just make sure you use enough rope and do not wind the spring too tight or you'll break it;

Best of Luck to you.
