Help! Sudden loss of power, loads of smoke and rattles

Thanks for the replies guys.

Fixed it last night on the work car park, thanks to my wife bringing tool supplies!

It was just the timing slipped. Cam to crank timing ok, but the rear sprocket on the cam turned around 45°.... Or possibly the belt jumped? I have no idea how, as the sprocket was tightened in it's new position (couldn't turn by hand), and the belt doesn't look damaged or loose.



Reset it back to it's proper position and timed it to around 0.9-1.0 and it's running great now.

Can't understand how it was even running that far out. Just glad it's a cheap fix that only took an hour in the work car park.
