CB500/550 / Is this a carburetion problem?
« on: August 21, 2018, 08:58:02 PM »
Over the last couple of months I have noticed that cylinder 2 has been ever more reluctant to fire up - up until now, with a bit of perseverance, it has started and once the whole bike has been running for a while its quite smooth.
However at the last attempt I could not get cylinder 2 to fire at all (exhaust pipe is completely cold even after a minute or two, whilst the rest are hot). There is a good spark and timing is OK.
Is there an easy way to confirm if it is a carb problem without completely dismantling - is there anything I can easily do with the carbs still on the bike - I was minded to have them off during the winter as at least one is weeping very slightly, but I had hoped to keep the bike on the road for another month or two before the winter really sets in.
Any advice welcome.
