Ok i really didnt know too much about this bike? Got it in a trade from Leathernun666, It had a 3.5 tecumseh on it, but he threw in this 5hp tecumseh. I didnt know if it originally had a tav or just chain? I cant find any brochures on these or any others unrestored? I did put the tav on it because i wanna put a ski in front and take it throught the snow!!! It was a quick restore not a full restore. But the enigne was the most time consuming. What you think?
