I checked the brake booster last night with no change in idle. I did find a few problems with my choke though. First off the hose that supplies coolant to it is missing, and the spring inside the choke housing is broken. I've got a manual choke set up on my Samurai that I'm going to use for now. I bought the carb kit, and a few hours and lots of ziploc bags later the carb is all torn apart and soaking. It was like dismantling a big puzzle. Now hopefully I can put it all back together. Would you guys suggest getting a new mixture needle or any other parts while it's disassembled?
