carbs

[AlanD]

Hi Guys,

Polised and laqured my carb elbows today, i was wondering how difficult is it to rebuild the carbs, what should i watch out for and where to get the best kit to do it with, all help appreciated.

i have had the top off, taken the piston out with the diafram attched,and looked inside, to say it's a bit dirty is an understatement, should it look all shiney in there, or should it look grubby? the diafram looksnew though. oh its the air intake thats grubby and the piston with a black ring round the inside under the diafram.

Hi Alan,

Did mine with the kits Peter at LD parts supplies, didn't strip them completely but used quite a lot of what's in the kit's

Set them up again (mixtures and balanced) and it runs and idles perfectly. about £30 in all.

Bare in mind though you need to have access to a C/O meter and balancing gauge to set them up again to get the best results.

Ian.

Hi Alan

if you use the search function you will find lots of very useful contributions concerning carbs. It depends how far you intend to go: throttle spindle play, temp. compensator adjustment, equal throttle hight etc. etc. All very important for a good result.

I bought all parts from Burlen.

Good luck

when I did mine I stripped down everything I could apart from removing any screws from anything that looked important. Most things can be removed from the carbs with the adjusting screws attached.

I also didn't remove the needle from the piston. When I put it all back together it fired up fine and sailed through the emissions at the next MOT no problem.

Best thing I did was take shed loads of photos when I took it all apart. It makes a great reference when it comes to putting it back together again!

Thanks lads, makes it a bit simpler, looks like buying a balancing meter first then go from there. one thing i did notice, one needle collar is flush with one piston and the other was a bit proud, so it looks an adjusting tool too.



thanks for the input and help

Hi Alan,

There are some very good articles on carb rebuild here:

http://www.buckeyetriumphs.org/technical/technical.htm

They are for the TR250 / TR6 but the carbs are essentially the same as a Stag.

There is lots of other info on the site that is also relevant to the Stag.

Thanks Pete that link is fantastic, all the pics and how to's i need. thinking about a full rebuild now and i have found why i have popping on deacceleration too!! running too lean on one carb!! as i have one needle set diffrently to the other.

going to print it all off and turn it into a proper booklet so i can keep it.



Thanks

Alan

I was thinking of fitting a Holley (or large equivalent Weber) to my Stag engine. This was not borne of any experience but from wanting to enhance the engine slightly. But from what I've been reading here, I think now that I shall refresh my existing Strombergs and use those! The rolling road figures from National Day seem to bear out the fact that they are a decent setup for the Stag engine. And why fix what ain't broke?

I refurbished the Strombergs on my Imp Sport engine many years ago and they were wonderful after that, so long as the dashpot oil was topped up - every week! :shock:But aside from that, rebuilding them was a cinch, setting them up a pleasure and they did not need touching for years on end. A good carburettor - highly under-rated!

For most of the year my Stag hasn't run well it would rev to 3000 rpm then lose power

Several attempts to reset them didnt make them any better this included the MOT guy trying to set them as well. Apart from getting the emmisions through the MOT it wouldn't run any better.

In the end I admitted defeat and booked it in at Faversham Classics. They gave it a complete service. They spent ages adjusting the carbs couldn't get a reading higher than 0.7. I thought great no need to refuel ever again. then they got a reading of 16 with a final setting of about 3.

The end result is car now running better than I can remember. At its worst it gave 17.43mpg. 1740miles later on a trip to TSSC meet at Duxford last weekend it returned27.46mpg

Probably used more fuel than I paid Faversham:shock:

i have a full gasget set now with needles and diaframs. Would you believe i was recomended to a garage in a back street, i pulled up in the stag, looking at the garage!!! what a shock, paint peeling off the front, really grubby windows that you couldnt see through etc, curiosity got the better of me so drove around the rear, never judge a book i say.

out came 2 guys, big smiles older, about 60ish(sorry) all over the stag, bonnet was up boot up, then they had her on the ramp, fettling uunderneath, admired the engine, took the air filter out, i asked if they could rebuild them,told me the carbs were set wrong just from listening, how did they do that!!!

i was cobsmaked to learn that in its day it was a triumph dealer!! ( i didnt know there were any, i thought they were all BL)and both the guys worked on a lot of triumphs in the past and loved the stag enginethe best, easy to work on, 'strong engine' as they described it. so any way i've decided to give them a go,they even knew about LD, rimmers and Wards. Well just as i was about to go, an hour later, they took me to one of the workshops, they have an e type part rebuilt, you sould have seen the engine!!! polished was not a word i would use more like eat your dinner off it, and the gearbox too. part built body, and lead filled in places, i could see it, stuck up the corner was a Porche too. will let you know how they perform
