I'm not far from starting my blaster for the first time since putting in new piston and rings.. I'm praying that she starts and runs.. I just was wondering if i should have the choke open or not for the first run? I was thinkin just a little.. but wasn't sure.. Also.. in the process of doing the motor work i installed a rebuild kit for the carb. As of now the screws are pretty much bottomed out.. If some one could post me a link for jetting it.. or maybe even how many turns from the bottom they should be. Well sorry if so confusing. lol any help is help.. thanx
