For those that didn't see my thread earlier, I have a barn find TR6 that has been in storage for roughly 25 years. I am trying to revive it and get it running. I know nothing about these cars and especially the carbs.

I have done the following: fogged the cylinders, turned it over by hand, then by the starter, replaced the fuel pump, cleaned fuel lines from the pump to the carbs and I am now attempting to start the engine. I am currently pulling fuel from a jug and not the tank, since I haven't done anything with those lines or drained the tank yet.

The engine will almost run for a second at a time, but will not stay running no matter how much you pump the accelerator or use the choke. I know the carbs need to be gone through completely. The front carb is leaking out the bottom by the drain plug in the bottom of the bowl.


It appears to remove them is just the 4 nuts holding the carbs to the intake, the choke cables and the throttle linkage.

Is that correct? Any tricks to removing all of the nuts?

Should I try to clean and rebuild these myself or is there a trusted source that will rebuild them?

Thanks,

James

James,
You''re in the right direction. That it will start but no run points at the carbs being gummed up.

Taking the nuts off to remove the carbs, be careful that none are seized, due to proximity to the alloy. Lubricate the threads, candle wax (heat them first, care!) or PlusGas.

Burlen, or SU themselves are the people in the UK - can't say about the US.

If you have the 175 CD Zenith-Stromberg carbs:

Use an open end wrench to remove the 4 nuts on each carb. The bottom ones are a little awkward to access. Don't loose the little washers with the nuts.
You will have to loosen the tiny nuts on the spring clamps, & separate the carbs from the throttle linkage.
Send a Private Message to poolboy, he is the carb rebuilding expert. Very reasonable, as well.
The carbs will fit in a USPS box for shipping.
He will likely return your rebuilt carbs to you within a week, they will look great and work perfectly.

Pictured below are my Zenith-Stromberg carbs that poolboy rebuilt recently.

Sounds like you might find this helpful. R&R Carbs is section 19.15.11

Thanks... I haven't had a chance to remove them, but I feeling lazy and may send them off for rebuilding.

I did download the manual and it will be helpful.

Poolboy is the man. Its nice to support the enthusiast who have grown to become specialist on things.

That said, should you choose to do this yourself (and its pretty simple, really, and cheap as well to overhaul them yourself - all bolt off/bolt on type things), or just want to educate yourself, here's a great series of articles from the Buckeye Triumph site. I've found, generally, that their technical articles are a go to for me....

In the interest of time, effort, lack of knowledge, etc... I think I will just let poolboy do his magic.

Thanks for the responses.

You won't regret it. Not only does he do a fantastic job, knowing little adjustments & tricks that the Buckeye website skips over- all this at a very reasonable price- but he offers support when needed.
Afterwards, you can relax in the affirmation that the carbs are not the problem- it's electrical. smiling smiley

James - I'm confident that you will be happy with Ken's work on your carbs. I do however suggest that you try and develop a thorough understanding of the carbs in order to maximize the benefit of Ken's refurbishment. You should also give attention to the ignition side of the equation.

I got the carbs back from Ken (poolboy) and they turned out awesome looking. Hard to believe they are the same crappy looking ones I sent him.

Nice work Ken.
