tries to start but no fire...
Do you mean it doesn't start? Or it actually has no fire, no spark?
If you mean it won't start then you need to check the gas. Gas goes bad. If it's anywhere near bad gas, drain the tank, clean the carb.
If the gas was good, try choking the inlet of the carb with the airbox removed.
If you happen to have some some starting fluid or brake cleaner, give her a good shot with the throttle open and try that...
Hope this helps.....
