How can I do a compression test on a deuce multifuel engine? I realize of course the first step is to pull out all the injectors. But what then?

I've done this many times in gas engines with a compression tester with a rubber tip that you jam in the spark plug opening while cranking the engine, but I doubt this would work on a diesel.

Is there a specific guage that will clamp in the injector port? If so, where can they be found?

Also, what is the acceptable compression pressure for a good running, used multifuel engine?
