Congrats to member Scampin

At MIR two weeks ago. I have had the stub stack for years, but it never ran well and back then I wasn’t logging data. I knew it was hammering the air door open, but was afraid to really crank on the spring. Breaks pretty easy. First ran the CF housing at MIR, no stack. Needed to add fuel, then added the stub stack and it went 1 full point lean! Was already at .119 jet in the rear and .119 in the front with smallest rod. Pulled the rear jets out and went with a drilled .135 front jet. Then ran the 11.17, overlaying the .17 run and the this weekends run. It was a bit fat this weekend. I can go bigger rod to take care of that. Still have about a comfortable 1/2 turn on the air door left. It used to spike lean, then rich, then stabilize, with the changes. It spikes at the air door opening, then stabilizes. Lean spike lasts 1 1/2 tenths. Different bases from MIR and Cecil. Doubled the lean spike height with new one, but lost the rich spike. All this adds up to HOW IN THE HE DOUBLE HOCKEY STICKS, does Brian do this WITHOUT data logging!!!
