Hand throttle funguled

Whimper ..whimper,, My hand throttle is busted. the knob disconnected from the cable and shows no sign of the plastic part shearing from the cable.. can someone enlighten me? I tried to feed the cable back through the mounting but it bottoms out and won't show itself. hard to believe it is all held together by a piece of plastic.

It looks like it sheared off. Is that right?

That's what I thought but there is no sign of the piano wire and the plastic pieces have NO sign of a break The wire has an "S turn end on it and won't feed out of the metal ferrule housing on the back of the console.in the cockpit so I am stumped.. This is the type that had live wires hooked to the housing for a throttle light on the console. This is weird puzzle

Yes that's all I know about them . Mine worked when i got the car. Then i went to pull it out one day and the whole shaft came out with the black plastic half moon cross section tip that has no captive wire in it.. It is a mystery how it disconnected and gets put back... I am surprised no one has fiddled with the inner workings of their broken ones to figure this out. If I had a good replacement I would do the autopsy on this one. It is a rather simple and task to tug on a wire but turning the light on probably added hours at the drawing board .

Every used one I've ever removed was no good.

Mind if I ask why you use the throttle?

It's Giuseppe's giubos, not Guido's guibos, on my 78 Alfas

Its just a carry-over from my days in Porsches and Giuliettas. The rule I always lived by from the 50's was to warm an engine oil enough to get the temp needle off the peg at like 1500 RPM especially when the garage gets down to into the 40's in winter and the car needs some exercise. It seems to be the best way to set the throttle steady. The hand throttle allows me to walk a way from it. It's old school and arguments abound to drive the car at a moderate pace right off he start to do that but it's hard to change what works best for me. When the exhaust has lost it's white vapor and the temp is off the peg, I'm ready to go in winter. Then it's steady below 3500 RPM for a mile or so to warm up the drive train.

It looks like I'll have to resort to an after-market one .. I hate anything after-market and my curiosity how the original works keeps the old bean moving just like the Sunday NY Time crosswords and 5 star Sudoku. If Anyone has a busted one I'll take it and dissect it as a JA project.

useful thread on removing the cable from the console.
you need to remove a S retainer clip from the back (post #1) then squeeze the plastic tabs together (post #11)

aftermarket at CA
maybe you could keep your nice knob with "throttle" and just use the cable part?

Thanks.. my searches were so loaded with stray paths that I could never nail this down. It's projects like these that make old car ownership fun.. Not a RE rebuild or a blown head gasket. No money .. just exercising the noodle.

Makes sense to me.

Well now we are making progress.. The brass end of mine that holds the wire is in the housing ....so that part of the puzzle now makes sense.. Now to learn how it separated at the midpoint black plastic bridge.. Send me a PM on the cost to 02648.. and thank you for the response!
