just been out for a run, now it will not tick over running at 2-3000 rpm
any ideas what i have broken???
running 2 ltr pinto twin 45 dellortos

Start with the simple one...Has the accelerator cable got jammed meaning its not letting the butterflys close right up?

Chech the cable and the return spring. Is the cable old at all? If so, just take it prt if poss and spray the cable with a teflon grease. Did this 3 years ago, and haven't had a similar problem yet. Also check the choke cable if you have one.
Or you've buggered something else, but i doubt it.

cable seems ok and carbs seem fully closed?

seem closed? If you're not sure, wind the throttle stops/idle speed adjusters all the way out and see if the throttle arms come up against the stops. Then you know they're shut.

done that seems to be fully closed although the last bit seemed a bit stiff????????????????

bent thingy through the carbs? Apparently having your return spring at one end only can bend them.

thay where fine today until i reved reel hard ? thought it was the cable but all seems fine. seems like fuel is still getting through?????????????

do you have a proper throttle stop?!

Yup, sounds like a bent spindle

Marcus

what is the solution???

A new one most likely.

Things like that are precision items and you will never manage to straighten it.

However you should take the neccessary steps (as mentioned by Joel) to stop it happening again if it is the problem.

David

can it be replaced?

whaere do i get one and is it much of a job?
cheers tom

Defective misab plate on one or more chokes ?

Some have rubber components which have no problem collapsing inwards.
