Lately it gives me some trouble starting. Its about 10 years old. Each year I change the plug. I use stabil in my gas. I changed the filter this year. I recall another part in the gas tank I changed a year or two ago as well. Thats the extent of mechanical experise. It does start and run...just not on the first few pulls...irregadless of where the choke is. Sometimes after running for 10 minutes or so, if I stop and restart it, its very difficult to get going. My trimmer, with the same engine and of the same age runs fine.

Someone mentioned adding something other in addition to Stabil to the gas/oil mixture to clean the carb. Any ideas what that might be or what else I can try?
