I didn't think the early ones had the aperture .. . . probably wrong. I thought Bill had listed all the various types in another thread, but I can't find it. C.

? Front valance a replacement ? C.

Bill and Mark will be along soon, but do I spot an original black pear shaped gear knob ? If so, fit a burgler alarm - they are very scarce. [Tongue in cheek remark - not serious] If you are newbies you might not know that your car MAY be on an earlier version of the chassis (referred to as Mk 1) than most 1200s out there. Looking forward to hearing more. C.

No, just an Engine of indeterminate origin/provenance. Probably has High Compression looking at the head depth. Checking the V5 and obtaining the DVLA history file may tell whether it was fitted when the car was first registered. C.

Chances are that the oil seals have been put in the wrong way round. They are supposed to keep water from getting in and to let excess grease OUT. Have you checked inside the brake drums ? C.

No-one knows why the springs were ever marked FRONT. C.

Flange position, bore and PCD (hence gasket) is the same on 948TC, 12/50s and Spitfire 4 manifolds (but not 1200). Gasket is GEG702 Listings for 12/50 parts may be easier to find (but would be the same). Don't know who supplies the down pipe only C.

Brian, To find an exhaust, the engine size is not so relevant as the exhaust manifold you have fitted, which is a 948 TC manifold. Parts lists are available online or on CD from a number of places. C.

Sorry, after posting I reread the thread and see you have 1 1/8" SUs on a 948 manifold. The 1200 carbs are either 30mm single or 2 x 1 1/4" SUs. I would be inclined to get this sorted before thinking about the exhaust. Search the site for conversions to twin SUs for 1200 engine. And then there are camshaft options to consider. What is the engine number? C. Start with the manifold. You have the option of 948: http://www.canleyclassics.com/triumph-herald-948-oil-pump-and-manifold 1200: http://www.canleyclassics.com/triumph-herald-1200-oil-pump-and-manifold 12/50: No link, but likie the leftmost 948 - longer exhaust tracts than 1200, and larger bore Spitfire Mk II: http://www.canleyclassics.com/triumph-spitfire-mki/ii-mkii-manifold-details Spitfire 4 (Mk i) No link, but exhaust similar to 948 and 12/50 What have you got fitted? C.

Thanks for that. I was aware that it is far from a simple transformer and that the physics can be complicated (always struggled with hysteresis and stuff). Presumably, if the arc threshold of the plug gap (coupled with things like the dialectric, affected by CR) is increased by increasing the plug gap then this will require a higher voltage to pass the threshold, and a standard coil may not be able to reach the threshold. Thus, bigger gap, bigger spark, provided the coil can (is designed to) provide enough voltage? C.
-
In what way do the plugs determine the voltage? Surely it's a product of the turns ratio. I was tempted to advise against using a coil with high output as it tends to find weaknesses elsewhere in the system. C. Edit. I am aware that high compression, etc. may prevent sparking with a normal plug gap, and also that a larger plug gap can be driven by a higher voltage. Which is why on my (mildly) increase CR I use a plug gap of 30 thou with a Sport coil.

Yes, 12v non-ballasted. Standard is Lucas GCL110 Lucas 'Sports' [gold] DLB105 is an alternative preferred by many. Available from the usual suspect or Google them up. C.

If you take a wire brush to the Vac capsule you will find the Lucas part number (8 digit), and the vacuum spec. (let me know with the dizzie number and I can update my records!) If you currently have a 1200 engine then the correct dizzies are Lucas No. Car Type Stanpart No. Vacuum Vac Adv Unit No. Mech Adv at Dizzie 40743 High C up to 1964 Lucas DM2 208362 3-7 8 54415212 5 40791 High C 1964 on (Hit Cam) Lucas 25D4 208968 3-7 8 54415212 10 A very satisfactory replacement for ant 1200/13/60 Herald is : 41449 Spit 1500 Lucas 45D4 RKC5044 5-12 6 54424752 8 C.

Search the site. Sorry , link no longer available for starters Many opinions/views exist, as to whether this can be done to proper standards without very major engineering. C.

Long and rather bad tempered thread here : Sorry , link no longer available Bill is (as usual) perfectly correct. Good latches in good condition will work well. I had to examine loads of them at autojumbles to find a good pair, but I did and they've been fine since. C.[url][/url]

You might want to phone Woolies for some advice: http://www.woolies-trim.co.uk/c-304-adhesive.aspx No connection C.

Sorry , link no longer available may have a bearing on the matter. C.
