I have a early model 125 engine restoration project and the engine has spark,but the guy working on it says it's 180 degrees off. Meaning that the spark is occurring at the wrong time. He mentioned he tried to flip something around, but the key way doesn't allow for that. I realize this is not much info, but I'm hoping someone may have any suggestions on this? I haven't been able to find any info on timing . Any help on this would be greatly appreciated. Thanks,
Chris Lillback
