worth rebuilding my engine?

[NoDOHC]

A few additional pieces of info:

The engine idles rather smoothly for a dead face on a rotor, but revs very slowly (like it is running on one rotor).

We unplugged each rotor in its turn. The engine sputtered and died if the front rotor was unplugged, but did try to stay running. The engine sputtered and died almost as fast when the rear rotor was unplugged (still trying to stay running).

The engine would not start on either rotor alone.

This goes against my previous experience with blown rotaries, when they would start and run and drive fine (except for extreme gutlessness and very hot exhaust).

I guess I am not sure that this is an engine issue or if it is a fuel injection issue.
It almost acts like it is running very rich or has very retarded timing.

Maybe we can pull the exhaust manifold off and look at the apex seals, that will indicate if the engine is worth rebuilding.
