Running rich at lower idle speeds, but smoothes out around 1500 rpm's. I ran it up and down the taxiway several times, then back to the hangar, shut it down and felt the radiator and oil cooler to make sure the radiator was warm at both the top and bottom. After approximately 4 engine starts and taxi runs, water temp was approaching 210 F so I taxied back to the hangar and shut it down. Oil temps got up to 160.(stock Mazda oil cooler) after about 5 minutes of cool-down time, the water temp was back to 190 or less. No visible oil or water leaks. I am now pretty sure I am running a little rich, because during one engine start, the engine was faltering, so I momentarily turned off the high pressure fuel pump, and it smoothed out immediately. When it sounded like it was going to run out of fuel (only a few seconds later), I turned the fuel pump back on and the engine continued running. On one pass down the taxiway, I got up to around 4000 rpm and the aircraft was accelerating very rapidly. I have no doubt this engine has enough power to fly this aircraft. When it is not running rich, it is an EXTREMELY smooth engine. I just finished re-reading my MicroTech manual, and since I have the handheld keypad (panel-mounted, actually), it is very easy to change the mixture. I should be doing more testing and tuning in the next few days, and I will advise. Right now, I have to try to wipe this silly grin off my face. Keep building, guys (and girls), when you actually get to start the engine and taxi your creation, the fun begins. Paul Conner, 13b powered (NA) SQ2000 in Mobile, AL
