First off i apologies if this is in the wrong section!

Hi there. I have a little off road toy that needed a head gasket change. I have fone that and went to start her up tonight but its just cranking over not even attempting to start or even splutter. have put it all back together and everything timed up etc.
I have fuel and spark. I did set the ignition timing off the car. I'm wondering if the rotor arm has moved when I put the distributor back into place and on the gears off the cam. Anyone else got ideas?
It's a little 1.6 8 valve single point injection 1999 V reg.
