Jonsered 2054 turbo

[Bluebird]

Just fitted carb kit as I was unable to adjust carb properly. Now starts first time but will not come down from high rev.. Have I fitted throttle cable wrong or is there an air leak?. Any help will be appreciated . An old model but little used.

It should be fairly obvious if the throttle is being held open - just gain access to the carb where the throttle cable connects and try to push the throttle closed and see if the revs come down. I am guessing the idle has been turned down?

If the throttle is closed, the idle has been turned down and the saw still revs high, it most likely has an air leak.

Bear in mind you have given us little history of the saw, its servicing, issues etc.

Thanks for that. The saw is a friend’s that had not been used for many years and my pal recently tried to start it but it would not run. It was full of old fuel which I dumped and I then I cleaned the carb ( Warlbro HDA 119 ) and fitted a new kit. To get the carb off you have to dismantle the handle which is why I thought it might be something to do with the throttle cable or because of the potch in getting the carb off there might be a leak in the boot area.

Yea, you have got something  stuck there, we have all done it. Just the annoying part of working out where it is. A good saw worth having though. K

Have you reconnected the impulse line? that can cause a high idle speed.
