Tecumseh HS40 let er burn

Dang, your lucky to have a father that cares about your hobby. I can't find any 1970's area Tecumseh - HS40 or HS50 Engines in my area & the ones I do find online, they want $400.00+ for them & they are out of there insane minds.
Let me change my first comment, I did actually find a Tecumseh - HS40 4HP Engine thanks to a friend & member here on oldminibikes.com & I can not thank you a nuff Bob.
