Hey guys
Does anyone have a picture of the choke assembly on a tp or similar carby?
The choke on my TP was disabled before I got it, I just rebuilt the carb and would like to stick it back the way its meant to be.

I have found a few pics but can’t see what I need (the spring and spring loaded piece of plastic on the green gear that open/close the choke) I have noticed that there is a mark on the gear itself, does this line up with the adjustment lines at "A" ?

Cheers

your PDF file about the carby should have this side view
the carby I have apart has all the choke bits missing
what view do you need

Thanks again magna buff,
I need the first view you have shown there. I can just make out from that pic that a part of my choke (the little plate with the clear plastic tube over it) has been turned 180 deg to stop it from opening/closing.
I will try sticking it back to where it is in that pic and see how I go!

Turns out the choke shaft was bent, I straightened it out and now it works perfectly
However now the car runs too rich and splatters, smokes, stalls on a cold start
I leaned out the mixture until ran ok cold with the choke closed and now it runs too lean when warm :tired:
Any suggestions? I’m starting to feel lost....:beer:

Put the mixture back where it should be. Use the choke adjustment screw to get the right choke setting for a cold start. I had a carb TP once, same choke setup as the older Sigmas. The wax pellet in the choke chamber (the bit where the water flows through) gets tired and it is a matter of trial and error to set it right. You don't want so much choke that it splutters, and not too lean that it stalls when you accelerate with a cold engine. Check though that hot water actually flows through the carb otherwise the choke stays on. Check the hoses that go to the chamber, they can block up, and check that water flows freely through it.
The choke set screw needs to be wound in to get less choke, if you reach its limit remove the locking nut on that screw to give you more turns. Short of a brand new carb there is not much you can do other than trial and error.

need i say EFI works much better?

Thanks MadMax.
I adjusted the choke so it’s open a bit and doesn’t run rich at start up, but I have to let it warm up for a few mins or else it stalls.
The choke operates as it should do and only takes a few mins at idle till it’s fully open.

"need i say EFI works much better?"
Working on that at the moment (sorry about size, first time using the bucket)

Sounds like you have it spot on. That is less of a problem as the weather warms up, mine used to be touchy when cold too.
