Check compression and come back with the results. We can't tell you anything without info.

How violently? The engine is known to "stutter" in first and reverse in low RPMs.

I don't think it doesn't matters what you use leading or trailing since they should both see the same compression, And you need to leave one pulg for each rotor in or else all the air will leak out.
Alrhough I think trailing would be easier to get too.

I meant 2 plugs as in both leading plugs....not the trailing and leading...so both bottom plugs on each rotor
