TS1 Running Fast on Tickover

[Toddy]

Is it a Throttle cable issue ?

Pretty sure it isn't as the slide is opening and closing fully as it should. The only thing I can say is that the tickover screw doesn't seem to have any effect on the engine speed. I can only adjust the tickover with the outer cable. The revs don't come down quickly at all and when I do get it to tick over it just suddenly cuts out.

Is the tick over screw lifting the slide sounds like cable to me ?

If your tick over screw is all the way in it usually indicates a too rich pilot. Did the dyno operator alter your jetting?

Did you get this sorted Rich ?

Not yet mate, it's still work in progress.

does sound a bit like an air leak,have you checked carb rubber, or manifold, maybe a leakdown test ?
hope you find the problem,

This is how it sounds, if this works.

That sounds like an air leak to me Rich.
I know its not a definitive solution but block the exhaust and see if it still runs.

Not something daft like the mixture screw loose/ dropped out is it ?

Something to check ......The bolt or stud depending on which you chose at assembly that is located at front of the manifold is still tight or in place.
The one that screws in from underneath the manifold.
From experience ! So worth a try.
Mine was running great when I set off and it worked it's way out leaving a gaping hole in the manifold !
