would love to help- but first you need to read one of these... and then re-post your question so people can understand it.

 

Need to check the basics first, is it getting fuel, does it have spark, air filter? compression?

[QUOTE=beergut;3169812. What is that I can't read thanks

 

Check the basics like Kerbbirds suggested. The popping back on these is usually one of the signs of a worn camshaft exhaust lobe also. Pull the valve cover and see if the center lobe is worn down. It should be the same size of the intake lobes. These are pics posted by another member. http://i1311.photobucket.com/albums/...ps832eb542.jpg
