with mystery running problem. Will run for about ten seconds perfectly normally, then coughs and dies. Will not restart instantly, but if you leave it a minute, it'll do the same again! It's not fuel, stripped the carb, plenty of flow through the tap, even tried squirting carb cleaner through the intake - no difference. What are the symptoms of the CDI packing up. Or the coil? Sorry, it's a 2005 450 and I don't know much about it really, only had it a week or so.... Any help much appreciated. Dave.
