Throttle Sticking

[primalscream]

Hello everyone, Gavin here. The throttle on my SX is sticking open when revved at about half throttle. Problem seems worse when stationary. I have to turn off ignition to stop revving then its fine when restarted.
It also seems to be taking a long time to return to idle. The carb is a Jetex, do you think this is a carb problem or possibly a blown gasket?
Any help would be greatly appreciated!

Sounds like an airleak.

Where do you think this is likely to be?

Zorst / inlet manifold nuts loosened off or even cylinder head nuts loosened off. I'd check the zorst nuts first mind. If yer Simon cowell's been fettled it should be a case of a socket straight on if not off with the cowl.

Thanks Scott. Brass exhaust nut had stripped thread. Replaced it and fixed.
Cheers.
