Stihl 066 Shutter

[gr8mac]

Does anyone use the preheat shutter? If so do you notice any difference in operation?

I found a thread on this topic but it must have been lost.

I've used them before on other Sthil models when it gets below freezing, but can't say that I've ever noticed a difference.
