i have been told it will if you hook the power up to a 12 volt battery, however it didn't on mine. if you get a spark checker light you hook up to the plug you can turn it slowly by hand and get it just as good as a timing light. you always tweek a litttle after it's running anyway. good luck.

 

What brand? I used an old Sears one my Dad has. It worked on a 6 volt positive ground with no problems or changes to it, but I guess it could vary by brand and model.
