grats on getting it running !!..glad we could help..if you go to a open air filter like a k/n..your more than likely gonna need to mess with your air/fuel mixture pilot screw until you get it dailed in..any time you go from stock to after market air filter on any bike..it changes the whole system in the way it runs..soo..be ready to spend some time with the air/fuel mixture screw..from what i have seen and read from people working on the honda 70's..they had sooooo much trouble getting them to idle..run right with an after market air filter..soo..good luck..hope your task is an easy one !Sure is easy when you have the right info. The carb piston was 180 out. Adjusted the idle screw out some, re-oriented the piston and it was obvious by the throttle cable when it was seated proplerly. Started it up (had to hold the throttle open some...) and then adjusted the idle screw in until it idle half way decent. Adjusted the throttle cable so there's a small amount of play before it lifts the piston. Now I need to dial in the carb air mixture so it runs & idles smoothly. Also, the air box rubber piece that attaches to the carb is split wide open. Had a bunch of silicon gooped on it. I'm either going to replace it with a stock one or change to a K&N type. Any thoughts? Thanks a bunch for the detailed info!! :rating10: Saved me a lot of time and research.
