Had the same problem with a Honda 2 HP. Before ripping it apart
you might try mixing up a 50% mixture of gas & Berryman's B-12
fuel additive and with the choke on pull it through many times. If It
doesn't start let it set for a few days and try again. If it works you are
home free, if not disassembly is needed. Also check the filter if there is one.
Be careful with the B-12, it can melt paint and some plastics. Ongoing
use of B-12 per the instructions may help prevent future problems, it
has worked for me for many years.
