RE: Glow Plug
I don't really have any Idle issues on the smaller engines,, After the engine Warms Up and I get the Air\Fuel mix dialed in,, That may be partially due to the fact I run a lot lower Oil% than Most and mix my own fuel so there are Minimal Additives to inhibit corrosion. The only Non essential additives or Dyes in my fuel are what comes in the Klotz Oil's.
