I pulled the head ground the valves and checked the clearance before I sent first e-mail
Expert:  Wayne replied 19 days ago.

Thank you for that

That is good , you set them .006 and .009

so that is good

Then that leaves the carb, suggest a disassemble and rebuild

Customer: replied 19 days ago.
rebuilding the carb is not going to fix it from spitting back through the carb ,it was running fine and died kind of like ran out of gas ,still had gas in the tank but started spitting back through the carb when tried to start instead of compression going out exhaust ,just want to know if there is a problem with the plastic lobes on the cam shifting or the compression release messing up between the cam lobes

Lets do a compression test on it see what the compression is
