If starting spray or gas does not fire, then probably spark issue. Try jumper directly from battery to coil. If it fires then you know you have a short/loose wire in the starting or run circuit and can start chasing the wires to find it. If it does not, check a plug for spark, if none then could be the coil, or points/condenser issue. Might be just enough out of tune that simple adjustment will get it going again. Only adjust one thing at a time.
