Like all long suffering LBC wives mine thinks I smell rather too much of the TR6 after driving it. I think the smell is great but I do agree it's a little strong and it's mostly connected to the front ZS carb runnung rich.
I've been messing with these things for a year now and have got the rear one perfect (judging by the plug colour) but I'm damned if I can get the other one right.When I lift the air valve slightly at idle the RPM picks up indicating a rich condition plus there's some black smoke and black sooty plugs.
I've got the float level right and checked by removing the bowl with th carb on the car.
I've got the needle adjustment fully out so there are no more threads left to turn.
The engine is in great shape mechanically and I've got the carbs well balanced.
I've confirmed that the choke is fully off and there are no vacuum leaks.
I took the needle right out of the air valve to check how it fits into the jet and found there is a great deal of slop between them even with the needle fully inserted, but maybe it's supposed to be that way, I would check against the other carb but I dont want to dismantle it now it's sorted.
I've also confirmed that the needle has not slipped back up into the air valve.
So what's left, do I have too much slop between needle and jet? /ubbthreads/images/graemlins/confused.gif
 
Yea, and I bet you do! I wish some great mind would solve the Triumph rider stench. I vote with your wife.

I don't think anything short of side pipes will solve it even though I saw an extream extension of the standard exhuast pipes on this news group that would probable work.
 
Hi Graham,

Have you tried swapping jet assemblies between the carbs, to see if the overly rich condition follows the assembly? If it does, you've identified the problem. If it doesn't it's time to look elsewhere.

Not much help, sorry!

AltaKnight, Yes I think you have located the problem if as you say there is a great deal of slop between the needle and the jet.--Fwiw---Keoke- /ubbthreads/images/graemlins/yesnod.gif Sorry to hear it Pongs too. /ubbthreads/images/graemlins/grin.gif
 
I agree it sounds like the metering needle or jet is worn or the wrong size if there is considerable slop as you say. I would also make sure the carbs are identical and not individual replacement add ons if you plan on swapping parts. There are some differences in type depending on year. I would also check the float chamber plug o-ring for wear. Lastly check the mixture trim screw end and spring. Then there's the temperature compensator valve if the idles off in anyway.

I think even if you find your problem your not getting rid of the smell. I just keep buying those industrial sized bags of pretty nice smelling stuff of whatever the wife likes and the pong is gone (masked). I usually shove one under the rear seat and one in the boot. So I made the car smell pretty and she is happy for a while. Maybe it's different in a 6 but then it was her hair in the wind, then it was (and is) too hot, the seats are too low and I can't see out the windshield...Then the worst happens... she talks while I'm trying to listen to the O.D. engage...Then there's the other option...Leave the wife home!

You will continue being smelly after a good ride in a TR6 because the mixture has little to do with the problem. The problem exhaust fumes in the passenger compartment. Yes a rich mixture seems to make it worse but even a perfect mixture will not eliminate the fumes in the passenger compartment. Just another semi-educated opinion.
 
I have had good success with eliminating 'the odor' with the use of a windblocker type mechanism. Worth a shot, plus cuts down on that wind from behind as you motor down the road.
 
i have a diesel truck. you should get one and replace the fuel filters and bleed the water separator, then your wife will never complain about the smell from the tr. also get her to stand behind the tailpipe of the diesel when you start it up. garanteed results. /ubbthreads/images/graemlins/devilgrin.gif /ubbthreads/images/graemlins/jester.gif /ubbthreads/images/graemlins/cowboy.gif
