RE: Saito 100??
Build-n-flyer-RCU,
While learning my way around Saitos I found that they will run well with the LS needle way too rich. Many new users seem to fly them without ever touching the LS needle. I have watched people set up two-strokes and never touch the LS needle as long as they will idle at all. Perhaps the reluctance to tune the LS needle on a Saito is a holdover from people's two-stroke experience. I'm not at all certain as to the reason, but it certainly seems to happen.
A little unhappily, Saitos are shipped new with the LS needles set very rich. However, they run much more efficiently, smoothly, and reliably when properly run in and set up.
Hopefully, Wttiger 42 and his dad will be able to get their 1.00 set up well and be able to appreciate how nicely these engines run.
There is a lot of good information from many people available here.
