Reply To: Neptune model 500 carb/ Tillotson HS93A

[Edwin Howard]

I did do some research and found that that model of carb was installed from the factory on the Neptune model 500 (1970-1978), so not exactly a frankenstein of a motor and chainsaw but a 1963 motor and some parts from a 70’s motor. I have tried flipping the choke when it tries to die and it seems to spring back to life before quitting. Once I get some 2 stroke oil, Ill see how richening the mixture does, and if that fails, Ill try and reshape the needle back to a taper.
