When you design something yourself you are stuck with correcting the design problems. Something that threw me for a loop was vibration, I kept having screws vibrating out. The solution was to put in longer screws and locktite. I also had to redesign my throttle linkage, the linkage was not opening the carb all the way open at full throttle. Now that I have taken care of all the little problems I hope I can concentrate on making the car bulletproof this winter.
