Hello, I have been tinkering away at building my first bike and it has been a lot of fun problem solving but I seem to be hitting a wall. I have overcome many little things that have lasted days and I can see my success in solving one problem only to hit another wall and start over the process of not knowing why the engine isn't running. After many hours of getting everything in place, I finally had my first successful run today. I noticed the exhaust pipe was rattling more than I'd like so I pulled off and after about 15min secured it. However, after I tried to staert the engine up again I could not get it going. I was thinking my technique of letting off the clutch and pulling the throttle wasn't good enough or that I wasn't going fast enough but after a few tests at different variables (and not overdoing the plunger on the carburetor) the motor was just turning over again and again and couldn't make that jump to be fully running. When holding down the throttle the engine would putter but have no driving power and eventually would give up once I let go. What is the best technique to starting up the motor the first time and is there anything I am missing?
