Finally had the 13B running with a lot of help from "THE" rotary guru himself, Tracy Crook.  Tracy flew down yesterday in the Otter on his first real cross country (1.5 hours). I still have some problems to sort out but at least we had it running after a lot of diagnostic work and chasing phantom problems. It was a very educational day for me, but am still a neophyte at the rotary game.

The engine was severely flooding itself and Tracy convinced me that once the plugs are wet, you are only kidding yourself if you continue to crank until you remove the plugs and clean them. I have been trying to crank with some suspect plugs that I had thought were new. They came in the engine, but Tracy said they have run before somewhere. We finally resolved that the two things causing the extreme flooding were that the fuel pressure really was what the EC2 monitor was reporting (64 psia) and that somehow when I checked the impedance on my injectors that I thought they were the saturated type and they are really the peak type that require the resistors. Tracy flew the otter home this morning from TCAP and has some resistors coming priority mail which I should get Monday. Bruce Turrentine suggest that I just buy a new requlator from Advance/Discount auto. Will pick it up tomorrow.

Even with these two problems, Tracy was able to get it running and had it purring pretty good on the B controller by turning the mixture control full lean and setting the internal trim full lean. When he flipped it to A channel , the plugs fouled before he could get it leaned. We could not get a restart because of the flooding.

My wife commented on how much better the Otter sounds with the new gearbox and engine. Hope she thinks ours sounds as good when it gets all sorted out here.

Should be cranking again on Monday pm. Stay tuned.

Bernie Kerr, itching to get flying!
