Not sure the horse power but it’s got to be at least eight. Rebuilt carb runs but needs adjusted for full throttle. brand new fuel cell cost me 150+Shipping basically buying a fuel-cell and paying 25 bucks for a motor. Vintage Montgomery ward can’t find it anywhere on eBay or craigslist. Probably worth more than I’m selling it for basically just sitting in the shed at this point. Give me a call if you’re interested. 50.00 bucks for just the motor and ill keep the fuel cell.
