Last weekend I adjusted the Ignition and started the Ironhead, It starts very easy and sounds very good. Unfortunatly I wasn't able to turn off the choker of the Edelbrock carburetor, without cutting off the engine as well. I tried to make a lot of adjusting, but I didn't get a good result. This forced me to the decition of installing another carburetor to see how that works.
This weekend I installed a Keihin CV carbretor instead, this time with much better results ! but it's still not perfect. I'll try to install a fresh set of condenser and contactors in the magneto, to se if I can make it run more smooth.
