Break-in is in progress

THE key to the starting in my setup was to NOT rely on plugging the muffler stacks and priming to get fuel into the carb/engine, but to instead cover the carb with a finger while turning the prop to prime. Before, when I just covered the exhaust stacks to prime, all the prime would just drip out all over the ground. By plugging the carb off with a finger, the fuel has to get up in the engine to get a proper prime instead of just coming straight out of the carb and onto the ground. I did also follow the clockwise bumping with a chicken stick to get it going.
And the homebrew 80% methanol and 20% castor that I mixed is working just fine.
Man, this thing is really going to give the airframe a vibration test! If it survives the break-in then this CG Yak 54 should never come apart! Now I'm off to get the rest of this gallon of fuel through the engine and wake up the neighbors..
