h82crash, if you haven't used battery ign before you don't know what you're missing! i refused to use them until someone gave me some for free. they then sat on the shelf for a year until i decided to convert a weedie, wanted to kick myself for not doing it sooner. ch is the way to go just make sure it is synchro-spark or you might have to rig some type of throttle-coupled advance or maybe two separate sensors, one for starting then switch to the second one for running. maybe a switch on the throttle arm could do this to.
