I need help my Honda GX620 engine is not cranking over it fired up a few days ago but not since what can be going wrong?

These are the things i did to try to fix the problem
. Drained fuel tank / added new fuel
. New fuel filter
. Changed oil / oil filter
 
explain more about what its doing, when you say cranking over do you mean the pull cord will not move meaning the engine will not turn over or wont fire?
 
Check the wire going to the low oil shut off.
See if you are getting any spark.

Have your helper hold the end of the spark plug wire, while you turn the engine over. If he yells loud you have a spark:no: JK

If you have spark then I would move to the carb, and clean it out and the jets, make sure the bowl is working right and not full of fuel.
Before that check you air filter.
Have fun I love to work on small engines, it reminds me of the time when I work on my honda ct70
 
My engine doesn't have a pull cord its key start

When i turn the key to try to start it it doesn't turn over


Forget that last stuff I said, try jumping the batt to the car. How old is the batt? If wont start get a ohm meter and start check out your wiring. Do you have a fuse or a breaker some where?

We are getting more info. I always go to the carb first cause it always needs to be clean. But it would be easier to check the spark first.
 
I'm sorry, I'm not sure I understand... You say it sounds like it will fire up, you mean it spins with the starter, but doesn't keep spinning when you disengage starter? or do you mean it clicks, but starter never engages?
I'm sorry, your info just seems very ambiguous. Can you be more specific?!
