Saitos come from the factory with SUPER rich setting on the idle adjust screw. Follow the instructions to adjust it. You will find it takes quite a bit of turning-in before it settles in all of mine took about 2i/2 full turns. You don't want to do this until you have about 32ozs of fuel through it, which you say you have. It is not like a typical 2-stroke glow than needs little to no adjustment. Start with 1/8th turn lean and check transition. Keep doing this until the transition is bad and then richen it a little until the transition is good that is your setting.
I fairly familiar with the process but, on the US40 with a sidewinder Saito, the low speed screw is facing the bottom of the aircraft. That makes any adjustments while the engine is running difficult. I use both a tach and the pinch test to set the HS needle and that works pretty reliably. Guess I'll have to shut down, make an adjustment on the LS needle, fire it up and keep checking.
Yes!!! Given your configuration you need to have the patience you will be richly reworded. NOTE: Saitos also need a valve adjustment after the 1st hour or so of running. When it starts to surge you will know it is time upside is the adjustment is real simple.
