Same '87 NA that I've been working on, that had the major smoking problem. Now I can't get it to crank up and run at all, seems to be flooding. Basically if I pull the plugs out and let it sit overnight and dry out, I can get it to fire, it crank up, run good for about 2-3 secs, then starts blubbering and shuts off. Spin it over w/ foot to the floor it'll try a few times before it finally just spins and spins w/o firing. Trailing plugs are soaked w/ fuel.

Plugs wires ohm out @ 12.5-13 trailing 17.5 leading. Coils are less than 1k ohms, and it is sparking so the igniters must be good. TPS checks out good and in spec.

Injectors all have continuity and spec out @ 2.4 ohms. Secondaries were dry, primaries were wet, the nose of the primary for Rotor 2 looked pretty wet when I pulled them out, although both had fuel on them. Dirt stuck in one/both of them maybe?

Haven't checked the AFM yet, although I did unplug it and try it, made no difference. Also haven't done a compression check yet, need to borrow a gauge again. This engine ran perfect though 2 weeks ago, then last week cranked it up, billowing smoke, now won't run at all almost. Think the apex seals died, or just several problems at the same time?
