My son was riding his PW50 in the yard today and it was running great , and then all of a sudden it just died on him , it starts right back up and idles but when you give it gas it boggs down and acts like it is starving for fuel , I flipped the choke up to the first setting and it runs great with the choke on .. I drained and added fresh fuel , motor oil and injector oil is clean and full ....took off the air cleaner and cleaned it out and blew out the filter , pulled the spark plug looks like new ... put it back together and its still doing the same thing
ANY IDEAS GUYS ...THANKS FOR ANY HELP !!!!!
