SS80 advance retard springs

[rhyatt]

Hi all,
Side point ss80 and I think  that the springs are not pulling the bobweights right back to full retard.

I've had a look around for suppliers, can anyone help please?

The bike has a habit of kicking back as you ease it up to the when starting. When running it's fine, but I think the weights may not be returning to retard as they should

Thank you

Although it's a bit of a pain, you probably need to remove the auto advance mechanism to check what's going on. If the springs are ok, the mechanism should snap back to the fully retarded position after you have rotated it against the springs. Sometimes a good clean can restore them to fully working condition but if the springs are stretched or distorted then new ones are probably required. Unfortunately, they seem to be hard to come by in the UK although more readily available in the USA.

just an update on these springs - Draganfly have springs that are really close , so will be trying them - but I am trying to extract the 4CA advance unit.
I have screwed a bolt into the end of the unit to try to pull it off , but it doesn't come up against anything to tease it off the taper.

is it just a case of screwing in the bolt and tapping it  gently to ease the unit loose on the taper? please?
thank you

The auto advance unit has a tapered end and so needs a gentle sideways knock to break the taper.

OK cheers
