Rough tick over

[Vmaxiow]

Hi recently my max has started to idle rough, it stared a couple of weeks ago when the leads and plug caps were loosing spark. I have replaced all leads and caps check the coils and they are all good, it's charging well and has a new battery.

It had a rebuild a couple of years ago and the carbs have all been sorted it had a tank clean and new fuel filters and it's been used regualry since. Just wondering if there's anything else I can check?

End of 2017, full strip, clean and rebuild, it hasnt been sat around since either. It was running fine until the other week when the plug caps and leads started arking out I replaced them and all was good. But now it's started not idling nicely again
