now. the high idle problem is back, I have the carb tuning almost 100% spot on, almost being slightly lean so i save fuel a little bit ( as per recommendations on some sites ), I had to go for slightly hotter plugs as the cool ones were just fouling up under the correct fuel mixture, so once again, the car comes to a stop any were and the idle comes up to a "fast idle" id say it idles at about 1500 rpm ( no rev counter ) , so i went over all the cabling the choke settings and bade sure the butterflies were closing, and everything is as it should be, yet the idle remains high, I think i should just sell it and buy a Subaru. atleased if that breaks i have contacts for everything

The TR8 in this video sounds quite nice going about its business http://www.youtube.com/watch!v=FrRm0k4lvus Its a bugger when a relitively simple fault like a high idle gets you chasing your tail isnt it, hope ya get it sorted

yes it is, I know that the timing ATM is slightly advanced and that may cause the high idle but its been advanced to eliminate pinging, this is why I'm mainly thinking I should just buy a newer car and just hold out on a project car, a project as a daily doesn't work but I always get the damn itch For it ( no the itch isn't a "bad" kind of itch ;) )

Timing advanced to eliminate pinking! not likely, would make it worse

Advanced! Retarded timing will raise the idle and stop pinking, that may be what you meant perhaps. What gas are you running!
ginga4lyfe,
May 24, 6:29pm
nope, I'm pretty sure it reduces it

You're not mixing the two things up are you! Advance = turning dizzy in the opposite direction of rotation.

Maybe I'm getting mixed up, though that's how I remember it, anyways I'm running 98

old method of doing timing, not advised, advance till she starts pinking and back it off a smidge. very scientific haha, yeh advance causes not reduces pinking. its not something simple like a vacuum advance hose on a ported hole instead of a non ported hole is it! have struck this before myself and took a bit of headscratching before I realised that passenger side on a yank carb means the opposite to here.DOH.

Are you setting the timing with a proper timing light, or 'doing by ear'! If with a timing light you should be able to find out what the timing should be (google), then check what it is.If it should be say 8 degrees initial, and it is now 12 degress, then that is advanced.If it should be 8, but is now 6 that is retarded.Usually overly advanced timing causes pinking, but retarded also causes issues.

OK well I'm a bit confused, the timing is supposed to be 10 btdc I backed it to 8, I thought I advanced it maybe my head works backwards
jmma,
May 24, 7:27pm
Yep, thats retarding it
ginga4lyfe,
May 24, 7:32pm
I always thought it was advancing as the spark fores closer to tdc, ohwell, I set by timing light anyways

Retarded as in held back as in later as in not firing as early before TDC as it was. High idle would have me looking for an inlet leak. Try the old squirt of lighter fluid 'round the manifold trick.
I'm assuming there's not some idle setting screw you've missed.

use 95 or reg
ginga4lyfe,
May 24, 7:47pm
Why! a lower octane is more prone to pinking than 98, so ill stick to that

sell it Matty lol, that thing is giving you issues like the gtir gave me. How long have you had it now! and out of that, how long has it been on the road!
ginga4lyfe,

no were near the gtir jax, mine has more rust and isnt 4wd, its been on the road about half the time that iv had it, and if had it since the beginning of the year abouts ( I only got insurance on it last week coz i wasnt using it till then )

you had the head off for work, and the manifolds, new gaskets when replacing them etc you now have an air leak on the inlet manifold somewhere, either a port has had a hose dislodged or a gasket has shrunk ( or worse , just one small backfire has shifted a gasket or blown a piece out of one - and it will not be in any place you can see easily) ( and thats from one who has a blind spot for air leaks of any sort ) try a bit of brake fluid squirted along the manifold to head face - its not so inflamable as lighter fluid, and the smoke it produces will soon tell you you have found the leak, it is also heavy enough to give and altered idle speed instantly thus indicating exactly which area you need to investigate in

Listen, mate. drop me a line & I'll swap yer trumpy anchor for a nice little Briggs&Stratten.no more idling probs, & prolly twice as quick off the mark.yes, yes, I know, you'll be well up on the deal, . but hey, just the kinda folks we are:) :) :) :)
edit:: ^^ ^^sorry, mate it's late. (actually have a soft spot for trumpy's,. just talking some shite before fall asleep )

Ill be going over the manifolds thoroughly today I will try the butane trick and the brake fluid trick, its just annoying as this was the reason that i took the manifolds off partly in the first place and thought that by un sticking the choke mech i had fixed it, I hope i havnt blown any gaskets or had them shrink, they were some pretty meaty ones
ginga4lyfe,
May 25, 4:48am
Lol tbh. a brigs maybe a little more like clock work compared to this triumph , hopefully that has changed since im running the right spark plugs now, Im still a bit head scratchy that its only poped up after i went to a hotter plug ( maybe the mixture is now burning correctly xD )

right! how good are the carbs! any play round the throttle shaft! how did you set the mixture! sounds like a wear problem to me but answer thequestions and ill help you sort it!
