Hi everyone!
I seem to remember reading somewhere that ES125/150’s used a brass bush little end so needed a 33:1 mix but was changed to 50:1 as the newer TS’s used a needle bearing little end. Also did the 250 engines change in the way the main bearings were lubricated? (Lubricated by petrol/oil mix as apposed to the gearbox oil or visa versa)
Any thoughts/opinions anyone?
Regards, Neil
