The FSR is an OS, made before the FX series.
They made the 90 first and upgraded it to the powerful 1.08.
OS still makes the 1.08, but it has a rear needle and throttle body.
This engine has a real carb, OS 7d, one of their best.
These engines are very high quality and last much longer than the current OS line.
Please do some research into what I am offering and ask a friend how they run/hold up.
