Since I needed fuel, I decided to fly down to my favorite fuel stop, Halletsville, TX (3T5) to gas up. It is about 45 miles SE from Lockhart. I had about 12 gallons in each tank, so i= t was time to re-fuel. Well, I flew over and landed at 3T5, taxi up to the pump, and guess what.... the pumps were out of order. @$#%&%$ OK, now I have about 19 gallons and need to find some fuel. So, I head over to Fayette Regional (34R) (our favorite BBQ spot) about 30 miles due north. I= t wasn't the closest airport, but I know that they have fuel there, and their pumps work! I flew up to 34R and landed with about 15 gallons left in the two tanks, not too risky, but the least amount of fuel I've ever flown with to date. Well, the pumps at 34R were working and I pumped in 75 gallons an= d added over 2 qts of 2-stroke oil. After almost maxing out my credit card, = I taxied out, did a run-up, rolled out onto the active, and flew back to my home base, Lockhart. So, all I accomplished was filling the tanks and burning 15 gallons of 100LL, but had a great time doing it. It was kind of like going for a $100 hamburger, except without the burger. The p-port 20b ran flawlessly. Oil and coolant temps were below 160*F the whole way. Engine didn't miss a beat while cruising along at 197mph (per EM-2) @ 5100rpm (M/T prop dialed down to full coarse). I must say, the new LS2 coils sure appear to have cured the occasional intermittent mis-fire problem. The engine just hummed along as sweet as pie. As they say, life doesn't get any better than this. You guys/gals that haven't yet flown, don't dismay, your time is coming. Mark S. Lancair ES, N/A P-Port 20B Lockhart, Tx On Sun, Mar 6, 2011 at 6:21 PM, Bill Bradburry wr= ote: > Did you fly!
