RE: SAITO FA65
no ,matter how well made these engines are everyone is different and the starting needle is simply a guild line, hence the variation in the literancher. I've never had the 65 but I Do have 2 91 2 100 a 1.5 and a 1.8, they all are about the same. Now assuming your engine is already broke in the High needle starts about 2.5-3 turns and lean it from there. LSN if not already factory set I start even with the barrel and turn in 1/2 turn and work with it from there.
Lean the high speed needle to 300-400 rpm rich of peak. PLay with the low end until idles well. at idle pinch the fuel line. if it speed up and dies its rich on the low end, if it just dies it's lean. When correct you should get a good low idle, the pinch should get about 3-5 second run and your transition should should not kill the motor or have any hesitation. reset the high end, reset the low end.
