If compression feels strong, not mushy, it's fine. Rebound can be affected by thickened oils a couple days after last run, especially in bushing engines.

Many bounce these engines off rocks 'n stuff, and often they survive. I've seen a few dug out of damp sod, driven about a foot down, and needed nothing but a very thorough cleaning and a new NVA.

When you crash an engine (plane), if there is any sign that dirt has entered the carb, the best thing to do is not move the crank at all until you can tear'er down and clean'er out. Closing your throttle all teh way may well have negated this need for you.

If only every $60 mechanism in this hobby was so durable.
