Throttle pedal/cable woes

When I needed more throttle pull I used a tubing cutter and tin snips to carefully shorten the shielding on the end of the cable on the carb end so it wouldn't bottom out against the bracket or the shielding that is mounted in the bracket.

I also have that same bracket and when I had my M1 I had to bend the bracket in closer to the carb to avoid the angle you have. I just put an adjustable wrench on the vertical part and bent it. It bent pretty easy.
