TR6 TR6 TIMING QUESTION...............................

Re: TR6 TIMING QUESTION...........................

Ok Warren I begining to be able to interpret your description.
There is no vacuum coming FROM the retard unit..vacuum goes TO the retard unit from the bottom of the rear carb. I also think you are confused about the origin of the lines.
Because a hose or line runs under the carbs doesn't mean that it originates on the bottom. The origin is the point of attachment to the nipple on the carb
And for the sake of clarity, the carb nearest the cockpit is the rear carb.
I think it would do a world of good if you took a look at the illustrations in the Moss Catalog in the "Emission Control" section. We could save a lot of time rather than trying to explain the location of things this way.
And yes, the retard module has a little play in it, however it's not going to work unless there is a vacuum line going TO it.
Have a look at the illustrations.

My professional job of plugging the module off the dist.

These are the vacuum lines you are referring to off the carb?

... that lead to the emissions canister in the front right of the engine bay?

Neither of these hoses cause a increase in rpm's when disconnected?
 
Re: TR6 TIMING QUESTION...........................

OK - now we are talking.

Could you take one more picture that shows both carbs in the same picture from standing height? Maybe the other guys are already past that, but it would help me 'see' how she is currently set up.

My guess is that those carbs could benefit from a rebuild, which really isn't that hard (heck, I even figured it out with lots of help from Paul and Poolboy).
 
Re: TR6 TIMING QUESTION...........................

Excuse my ignorance. I am trying to gain as much knowledge without being a nuisance, but once I ask one question they inevitably lead to more :smile:

I found the nipple coming off the bottom of the rear carb :wink: I should plug this just for the timing or keep it plugged?

Thanks again

Re: TR6 TIMING QUESTION...........................

No worries Warren, that is how we all learn.

The two thicker tubes from your post above should go to a black canister near the front of the engine bay, they are there to catch fuel vapors and should remained connected when you are tuning.
 
Re: TR6 TIMING QUESTION...........................

There is NO need to plug the NIPPLE on the retard unit. It Does Not generate a Vacuum. It is designed to RECEIVE vacuum from the rear carb's nipple that you just discovered. (Sorry about the "caps" but I seem to be having trouble making that point.)
The hoses that you are highlighting in the photos are not vacuum lines per se. They are ventillation lines and also the conduit for the Anti Run on Valve, but I think it's premature to get into the explanation of that system.
Just cap the tiny nipple on the bottom of the rear carb, for the time being.

You're not being a nuisnace,but I'm sure you realize how hard it is for both of us to describe the plumbing without using the visual aids available from the catalog illustrations.
You think the 73 is complicated, be happy you don't have a 74 thru 76 to get familar with. Just compare the illustrations, you have it easy.
 
Re: TR6 TIMING QUESTION...........................

I know my vocabulary sounds like a dyslexic 5th grader, but I promise I am trying...

Plugged the nipple on the rear carb and readjusted to 12 BTDC with ~900 rpm's at idle and adjusted the mixture to run a little richer after using the "lift the air-intake with a screw driver" approach of finding the correct mixture and she seems to be okay... so far :driving:

Appreciate the diagrams. More to learn... All my other hobbies seem to be moving further and further to the rear :smile:

Thanks again for your patience and tutelage. My new approach to questions will be littered with pictures!

Cheers

Re: TR6 TIMING QUESTION...........................

Yep, and if you're a married man, your spouse will notice a little more delays getting to the honey do's and the grass may get a little higher between cuttings, etc, etc.
Oh yeah, you'll be spending more time on the computer, too.

Re: TR6 TIMING QUESTION...........................

You do have a lot to deal with, Warren. Next time I'll try to take that into consideration.
 
Re: TR6 TIMING QUESTION...........................

Well congratulations. You might be surprised about how this might work out. I actually got into this whole deal with the arrival of our first since I needed to keep myself business since we weren't going to be being fabulous anymore. I decided that I needed a hobby and despite having never picked up a wrench before I'd been a car nut forever...

So, just tell you wife that you picked this car up so you could be close at hand rather than doing ______________ (insert less palatable activity that your wife hates here).
