Yup, Start with the basics...

Fuel. Turn the key the the start position, if you hear the pump kick on then you go to spark. If, not check your main relay.

Spark. Pull the plug wire off and put a plug in it. Rest it on the block and crank it. If it has spark go on to the next. if not, check the ignitor in the dizzy.

Check your timing...

There are several small factors in a Honda motor. Start with the small easy ones and work your way to the harder ones.
