Keep us posted on this, but I would not place too much faith in these magic elixirs. My Ariens has improved over time with Seafoam, but still hunts at full throttle and refuses to idle without full choke. Other adjustments are needed in my case, and probably yours too.
Today being the second day of Spring, we are naturally enjoying the largest snowfall of the season. Earlier today I managed to get the Ariens to start, with great difficulty I might add. After just enough passes in four inch deep snow to get a car out, she stalled out for lack of fuel. Took a ride downtown, got some gas, filled her up and attempted to restart. Would you believe that SOB refused to start?
So by now the snow is six inches deep with at least another six expected. Obviously it was time to get serious unless I wanted to move a foot of snow by hand. Pulled the spark plug, after removing the muffler heat shield that prevents you from removing the spark plug. Brilliant piece of engineering there. The plug required effort to remove with a 1/2-inch ratchet, all the way to the last 1/4 turn. Some of you probably already know where this is going. The plug was dark and wet.
Cleaned plug with wire brush, gapped plug, then blew if off with air. Installation also required effort the entire way, and it seemed to require more turns. After that the machine started instantly, no popping or hunting, and easily moved nine inches of heavy wet snow later in the day. This machine is running better than it ever has. My theory is that the person in China who assembled the engine cross threaded the plug, and he stopped tightening before it was fully seated. If that be the case, I have a cross threaded plug in a machine that now runs well. I was hoping to put in a Platinum or Iridium plug, but now it seems that perhaps I should just leave it alone. Your thoughts?
