RE: SPA engine options
I got a YS 61 ST1 just for the SPA. The engine is basicly new but the carb o-rings have dried out. I have found every YS 61 version manual except the ST-1 heli version.
Please does anyone have the 2 page manual to send a copy to me. I will pay if need be...........This is the metal regulator housing and 2 needle carb with idle set with reg screw.
