Is there suposed to be a return spring on the choke? I pulled mine out and it doesn't seem to want to return to the open position. I can't push it in and can't pull it out any further. Can't find about it in either the parts manual or the factory workshop manual.
So what am I doing wrong?

Help! Help!

Hey, Dick -

I think you want part # 28 here.

Mickey
 
so are you saying you cannot push the choke back in? Or you can push the choke back in but the carbs are not returning to the off choke position?

I do know that some of the chokes have a function that you can turn the knob to say the 3 oclock postion and it locks and keeps it from going back in. if its stuck in the out position try twisting the knob a little as you try to push it back in

Dick - as Mickey says, there should be a small spring (#28) on each of the H6 carbs, to pull the jet back up. Choke knob/cable pulls the jet down to enrich the mixture; spring pulls it back to "normal" position.

The choke knob itself may (or may not) have the "full rich" turn-to-lock, but there's no spring in the knob/cable fitting.

Tom
 
The original choke knob did have the "turn to lock" feature. Not just full rich, but 3 or 4 places between off and full rich.

If turning the knob won't free it up, then IMO you likely have a problem with the choke cable itself. The return springs are important, but you should be able to push the knob in without them.
 
I, too, am a bit uncertain of the complaint. I assume that the knob will not be pushed back in. If the knob feels "springy" when you try to push it in, the lockup is probably at the carb end of the cable. If the resistance is hard, probably at the knob end of the cable. Do try turning the knob and pushing incase you have a locking cable.

It's gotta be the lock feature. Turn the knob to the right a quarter turn while you push it in. On a 1960 the lock is automatic...you have to turn right to release.

John
 
Two parts to the problem. On the front carb the return spring #28 was not hooked up (operator error). Plus it does have the lock feature. Turn the knob to the left to "unlock".
Thanks a bunch folks.
One more item off of my "TR start attempt, to do list".

Dick - congrats on "one more step in the right direction".

I think we learn something from nearly every post on BCF.

Got that right, Tom! :thumbsup:
 
One more example of "Rightie-tightie; leftie-loosie".
 
RHD tight...LHD loose??

Hey, I was intrigued Dick, so went and checked. I have an original choke...it turns right to release. I have a Moss repo choke...it turns left to release. So, I guess it's a case of my right AND your right! Or, is one for RHD and the other for LHD???

John
 
I shall defend your right to hold your right, right on forever.

Unless your right up-rights my right.

PS - my choke knob locks when turned clockwise; unlocks when turned counter-clockwise.
 
Worse yet, my Moss replacement choke (not really a reproduction but looks pretty close) can turn either direction to lock, and you turn it the other way to unlock.

I really like it though, as it will lock in any position (rather than having definite notches).
 
Actually Mickey, mine is auto-tightie, lefty-loosie. Mine came from TRF so go figure Randall. Maybe they all don't buy from the same vendors.
We can have a whole new section at the big concours shows depending on your choke turning orinetation. Whohoo!
Now if I can get it to stop leaking.....................

Dick
 
Leaks are a good thing...think of them as automatic rust protection for the undercarriage. And, when they stop, you know it's time to "top up"!
 
Well, true. Unfortunatly this is a coolant leak, sigh. Might get to work on it tomorrow and will find out more about where it's coming from and how bad, etc.
Cheers, Dick
 
OK...Now I'm humbled. Only a real man would drive a 50 year old Triumph to work in the summer in Tennessee!

Like they say, "when you cool, you cool all the time"!
