Hi,
Can someone please point me in the right direction for setting the timing on a MX250 with standard ignition components?

Cheers Mark

Jam a dial indicator down the spark plug hole & rotate crank until the piston crown is 2.4mm Before Top Dead Centre (BTDC) then align the two timing marks shown in your pic. That should be pretty right

YEp how easy is that ! if your real lasy and just wanna see if it runs shove somthing in the head that point out, find the point it hits highest spot mark it and cam back a poof tenth. ( couple a mm in tech terms)

and if it dont run you got other issues
