Just got all the stuff to uncork my L, Pipe, air cleaner, smog blockoff, and carb kit. The kit is by Dynojet, has a couple of jets and a spring and a long, thin shaft/needle. It does not mention drilling 2 holes like Daves does, and does not have a small thin washer to raise the needle, I've read you can get the washer at Radio Shack, what size and thickness?? And is drilling the 2 holes larger the only diff between this kit and Daves??
