carb balancing with bal needles

I bought some BAL needles of Wayne S last year and have only just got round fitting them........

once fitted, my car would hardly run so cleaned out float chambers fuel lines etc. as it would run (a little rough on tick over and if you took it over 30mph it just wouldn't respond)so popped out my plugs black & sooty thought hmmm........ running a little rich put some new plugs in and fired up took it for a spin around the block phoned the mrs too let her know I was going to be a little longer as it was running quite nicely after about 45 mins of spirited driving along the country lanes on the outskirts of Blackpool got back and whipped out the plugs a nice brown/grey colour with a little black on the threads I thought hmmmm again.......bit of residue left from the old plugs me thinks
I guess it was running a little rich with original needles so spoke too rick at S&S who told me to get my carbs set up.
its amazing how many garages don't want to do what you would have thought to be simple things like tuning carbs about eight phone calls later finally i finds someone locally a group of ex TVR engineers still working in the units of the old TVR factory a quick test with a probe in the exhausts told him it wasn't running rich so off with pancakes sticks his carb balncer in the first carb it read 3 pops it into the second carb it read 9 a little inbalanced to say the least (seems I was only running on 1 1/2 carbs) anway now there balnced and running properly looks I will be driving too Billing.......

thanks again wayne (over 12 months later lol)

It rides again..... and again wehey!!!!!!!

Yep, same problem is starting to appear in Oz these days. It's just
cost us a fortune.

While tarting up the 8 for our show last month, I discovered the
diaphragm in the vacuum advance on the disy was passing air, so
must be split.

Went to 4 different people, locally, [where many are old school, &
know old stuff], for a new one, & only got, "don't know nothing
about them old things" type answers.

I had the son who was home for 10 days leave, specially for the
show, ring the Rover V8/TR8 specialist interstate to get
one. They must have good salesmen down there. What he actually
ordered was a ported high performance manifold, special big
throttle body plenum, & a complete Mallory ignition system.
Impetuous youth.


Of course, he had to go back to sea before this stuff was half
fitted, so I was the one who discovered that none of the sensers in
the old system fitted the new stuff, the triggers were different, &
I had to find a lap top running on windows 95 to get the computer
tuning disc to work. I finally found a bloke who knew more than me,
but what a hassel, & damned expensive.

Carbs for me for ever.

Oh, yes, it now only takes 2 seconds to get to illegal speed, rather
than 3.

This is where clubs need to step up & accumulate a selection of specialist tools, analysis equipement & of course, the knowledge of how to use them.

Cough! Cough! Ahem, Kind Gentle Men. Would it be too much to politely suggest a glance around you at the accumulated wisdom within these humble portals? Can it not be seen the souls hereabouts with the knowledge and help-fullness awaiting your pleas for aid?

Then there is that small matter of the lonely SEARCH function above your right hand.

Carburetion? We got you covered. Gearboxes? We got that, too. Cooling system woes? No sweat, G.I. Our community may not be the biggest, we will squabble on occasion, and rust never sleeps, but let no one say we can't get you thru the crisis of the hour!

Sorry you have a sore throat there Mildred. [:)]

I agree that the forum is all knowing & a modern miracle but sometimes just having the right spanner is more valuable than all our rantings combined (mine in particular).

Maybe it's just this part of the country but I'd rather fix it myself or learn how to fix it myself than tried to track someone down that knows how to fix it. We do have a garage owner that is in the club that fixes our old British cars (he has an E type Jag) but he is a long way away and you have to pay him real money. I haven't got to carbs yet but I will when I get to getting Yellow TCT to the running stage.

Ron said at last weeks car picnic "Your exhaust pipes sure are clean" (not a spec of soot) and I said "That's what an oxygen sensor does for you". [:D]

best bit when it came too paying......... he said just put some money in the pot for tea and buiscits (cost me a tenner)

It was nice too see such an array of vehicles in there jag xk120, a TVR vixen, sagaris, tuscan, a proper not a kit car lambo, countach complete with rats nest in the glove box for restoration also had a space frame race car with a fireblade engine in the making and a couple of austin martin/jag V12s engines in the process of re-build oh and my humble TR7 which I have too say looked a little, understated, wish i'd have taken my camera
