Heya Brad well as far as the linkage go's that all depends on whether you got one with a slide or rotary carb. Mine came with the rotary so I have been using everything as from the stock car header, Pipe and linkage as well as flywheel and clutchbell and gears. Yeah we could chat some time. My carb actually wasn't holding fuel at all. I had to switch carbs from my 12RSS to my FR15 since it wouldn't hold fuel. Mine also came with no tuning instructions so I just did it all like it was the 12RSS since the motors are very similar. Later man.
