My kicker is a 2006 Honda 5 hp. I last started it without problems in May. The otherday I pulled the choke out and pulled the rope and it started but was lugging badly. I couldn't push the choke in without it stalling. I changed the fuel filter and cleaned the sparkplug, waited about 15 minutes and it started right up and ran like a top, both in neutral and in gear. I put some Stabil in the gas and ran it for about one half hour. Today when I tried to start it I was back to square one. It just lugged along. Any suggestions before I take it to a real mechanic? Thanks.
