Silly question, but does the throttle cable come apart, where the 1 splits into 2?
If so how do you do it?

not by design as far I know - although with brute force and ignorance anything come apart... just depends on if you want to use it again afterwards...

Well, it splits at the plastic box, one section going on to the carb, and the other to the auto lube pump.
It's a well known area for problems with sticking throttles, and for this reason I drill a small hole,[just large enough for a WD40 straw] to fit in to at the top of the box, and occasionally give it a generous squirt, but best to do this when the tops of the carb.
As Mark said though, I can't remember whether, by design it can be dismantled in a non destructive manner, if in doubt, go with the above idea, carefully, to avoid snagging the inner cable cores.

I only ask because I've damaged the top cable when I hit a tree. I have got a spare throttle set, but didn't want to change everything.

From memory only, I'm almost sure the top of the joiner box can prised up, GENTLY, and the top/throttle portion of the cable replaced, which would also be a good time to oil the auto lube cable as well.

Thanks mike, will look tomorrow.
