Anybody have an idea what could be the cause.One of my G/S's starts easy and goes well until it is warm then starts backfiring and have no power. After a while it runs OK again but only for a little while then it starts again.
I have an idea it might be one of the carbs but dont just want to start stripping and maybe screw it up even more.
Any ideas/help appreciated
