Hello ! I hope you don't mind me asking ,, Does the seat spring support you O.K. ?my servicycle spring is way too weak for my skinny butt ( 170 lbs) keeps hitting the fender if I don't dodge cigarette butts , Engine looks frankenstein , but should do alright if it's tight that early belt setup might drive you nuts at first ( like it did me) once plumbed up , it does alright , Please don't hesitate to ask stuff , these engines are very " different" and have specific idiosynchrocies b( hope I spelled that right ) thank you for the excellent photos and good luck with your project , Larry.
