Brumby Throttle Sticks

I have a 90 Brumby. On the odd occasions the throttle will stick on. This seems to happen on really cold days until the engine warms up but doesnt do it all the time. Jams up on full noise and gets a little exiting.

Stop and have a look and nothing to see as it has unjammed????
Feel like it has something to do with the choke??? The hose from the exhaust to the aircleaner is not there also. Any ideas please.

I'll second that. You can loosen the screws and twist the auto choke casing to release some of the tension on the spring, this might help - if you have a manual best to consult it for correct adjustment.

The pipe from the air filter to the exhaust is for warm air in the cold - it helps the engine warm up and stops the fuel from freezing as it changes velocity (thus cooling) in the carbie in cold weather...

All the best with it.

Had this happen to me in my previous brumby, But it had also developed constant vacuum every ware causing the choke and everything to just stay on.
