Hi folks
Returned from ace cafe run and the buggy ran great apart from one slight annoying traight

When warm the engine idles at around 2000 rpm

It pulls well and performs as expected just idles high
Carbs are all on there stops linkage is fine
I think this started happening after taking off the carbs and giving them a good clean. Could now they are clean be the issue??
Twin 44s so no choke so not that

Ideas?

Cheers dav

Possibly heat expansion on the engine putting more tension on the throttle linkage may be needs a bit more free play or the throttle cable gets warm along side the gearbox and starts binding

Not sure snoopy, as I have the cable link sync linkage.
When it's ideling high I've checked the link of the stops and they're bang on.

Could it need the idle screw adjusting now I've cleaned and sorted the carbs??
And can I just adjust this or will it throw something else out, like mixture etc??

Cheers

you can adjust the speed screws without upsetting it but they need doing the same amount on both sides to keep the balance.
