Help - stuck throttle

[JohnFairfield]

Help

After an enthusiastic overtake this morning the throttle on my t350 is stuck at about 3500 revs at idle!
Driving is difficult and noisy, but not impossible.
Anyone had this problem? Any ideas for a DIY fix?

OK found the problem.

I feel rather foolish!
I topped up the coolant header tank this morning and must have left the cap off. It had got stuck over the butterfly adjusting screw for cylinder one and was wedging it open.
Removed it and all seems well!

Lucky me.
