Hi Edward, great to hear that things have gotten better at your side. Just a feedback from my side on the BRB, I had the p/s in a Max Fantini crankcase, had a run last weekend, I just have to say this...the performance is simply AWESOME!! The idling is SWEET, and the power is very handy when needed. I ran it last weekend on a small track, gotta hit the bigger tracks to test out the baby further. All in all, for the moment, I'm impressed with the GEM.
Darth Vader, give the PR12 some more run time, I'm sure the seating of the p/s will only get better. FYI, I checked the needle settings on my engine, it's 4 turns 5 min on the HSN (

...and it was running around 110 last weekend under the hot sun!), and 2.5 turns on the LSN.
