Do the simple first- replace the spark plug.

Does the prop hub have a key way on the crank..................prop hitting the ground in a crash could move hub if a key is what holds it to the crank starts to shear off.....would change the trimming if the key moved.

Too early ignition timing also causes occasional misses.

The spark plug boots will often leak when under compression only. Spark looks fine when not installed? If it was damaged at all in your accident, I'd replace the ignition if you have one you can swap into it. If that works, order out a new boot and just replace that?

I have seen the same symptoms on a club mate's plane where the spark plug cap wasn't properly on the plug.
He had loosened up the spring clup on the boot too much so you could see the cap moving up and down on the plug

LOL, A club mate was also complaining about his RCGF 55 missing in flight. So I said I'd take a look at it.
So I walked over to the plane and paced around it in circles 2 closckwise and once counterclockwise and exclaimed EUREKA!!! and walked back.

After I sat down he looked at me and Said: I thought you were going to look at my engine?

I replied: I did, but not just that, you'll be pleased to know I found it under the cowl....
