Got a 6 month old Super Recycler MOD: 20384, that don't start quite as easy as it did when i first bought, but will after cranking for longer then i should have to. Then runs quite rough for a minute or so, and eventually will smooth out. I just changed oil again and looked at the plug, which seems good. Haven't bought a new plug yet. Do you guys think the plug may be going bad or should i look at other things? Always using fresh gas, by the way!
