This weekend while doing some maintenance on the r90/6 she started running really rough. The long and short of it is the right side was not firing all the time and after taking the carb off for a cleaning with no results I'm thinking the coils may be bad. I located two replements via a local parts dealer that should be here tomorrow. ( these are 6 volt vw coils). Does anyone know of a cross over part number for a set of points? I am try that tomorrow if the coils don't solve the issue. Thanks,,.
