Thanks for the good words, Ron.
I had a feeling my post might be a little confusing. I was running the engine. I only pedalled to calculate my speed. I was careful to pedal lightly and not increase speed. Maybe someday I'll pry the wallet open and buy a speedo.
Yeah, it was a cheap build. These old Schwinn Continentals used to be easy to come across, even in the garbage. The recent trend of converting contis/varsities into fixies might have reduced the supply a bit. I was taking a chance building with a $10 used leaf blower. I don't know how old or worn my engine was when I got it. The black fuel lines were crumbling in the tank. Luckily the carb wasn't clogged. But I got about 2000 miles on the motor last year, so I've already gotten my "money's worth" out of it. If you can buy a china-motor kit for around $100, that's a small price to pay for a lot of fun.
I wish I took pics during the build. I'm thinking about motorizing another old Continental with a Craftsman weed wacker my brother-in-law gave me. I'll take pics during that build, if I do it. My plan is for it to have a combination friction/chain-drive with 2-speeds. It's top-secret, so that's all I'm saying for now!
Drive wheel is 1 1/4 inch, BTW.
