Hello flatlinerz,
Sorry to hear your machine is not working.
If your engine was working ok before the air filter change.
Then it is likely that how the filter was changed has caused it to stop working.
If something I have done has caused an engine to stop working, I usually put it back the way it was and see if it still starts.
From what you have said, things that could have gone wrong:
1. is it the correct filter and installed the right way.
2. did any foreign particles fall or get sucked into the carburettor whilst changing the filter, like grass clippings?
