westwood s1300 will not start new plug plenty of spark/ new oil/plenty of fuel but will not fire

If you have a spark then it's either lack of air or lack of fuel.

Modern fuels tend to cause the fuel lines to perish - air enters where it should not - consider having it professionally serviced - or buy a fuel line kit - I think Amazon have them.

This is mere conjecture...

Good Luck..., March 2017
