Lance GS-R 150 HELP!!

[Marliey]

Ok so I am 60 miles deep in the desert, with no warning I loose all power and when I try to start engine turns easy but will not fire.. getting fuel, healthy spark, compression and air... only thing I can think of is timing?...I am not timid but do not know how to go about it IF that is the issue.... please help!

Unlikely it jumped time. You can check if you pull the valve cover and remove the spark plug. Put a straw in the spark plug hole and and watch the timing marks as you turn the engine the straw will tell you where the piston is in relationship to the tdc mark. Also if it jumped time the cam chain would have to be pretty loose check that. You say it has compression but turning over really fast means no compression to me... Maybe bent or stuck valve...

Kinda what I was thinking.. Thanks
