This rod came in a plain jane 50 which I ran today, it's now black with chrome rocker covers.
I have the later 125 with the larger cooling fins, I had a 115 briefly and when the first 125 came out I sold the 115. I think it would have been a fine engine.
Saito 50 that came with the rod shown above., now has new rod, bearings and gaskets.
Fuel===Wildcat 10% full synthetic.
Prop====Bolly Clubman 11.5 x 6
Plug====Glow Devil for Saito/Enya
Exhaust=Late cast muffler
The engine turned a little stiff, I was concerned at first
The compression was a little soft but started on the 4th flip
It went right to 4,000 rpm so I did not touch anything for 10 minutes.
Then I moved it up to 5,500 for 10 more minutes, 1st attempt at full throttle was 10,100 rpm
Then to 6,000 until the 14 oz tank was half empty.
Max rpm art half tank===10,580
Idle at that point========2,100
It now turns freely and has snappy compression.
I was overlapping cutting logs to 24", so no pictures.
Ancient Remington electric chain saw broke into 4 pieces for no apparent reason. Fun day, time to read a book and study for Christmas play.
