In a situation like that, the engine stops, then I tweak the compression adjuster a little bit, and try it again. Usually you can eventually get the engine to run long enough so that you can better adjust it then.
Looks like a nice day to play with engines too. It is always fun to have a engine do what it is supposed to do, that it actually run.

I have read about some people before having their engines fire up and run a prime off, from nothing more than WD-40 or something being used to oil them up with.
I don't think it would be fun, it is was a big engine either. I haven't had it happen to me yet.
