Didn't do a lot today, Sunday and all, but I did remove the stock muffler and fabed up a header flange. Fixing to start bending some of this tubing I have and I need to refill my gas on my mig welder. Going to bend a header pipe that goes out over the back tire. Making threads to screw on a muffler like Karen has on her Tom Thumb with the 79cc engine. Speaking of which I got my 4.10x3.50-5 tires and tubes in and should get the tri-stars and axles, throttle, hand brake lever and such next week. That's about it for this week. I have full size plans drawn up on a computer and it really helps making things to dimensions and knowing they will fit.
