Soooo, Radiator top and bottom hoses fitted These are made from Marine spec single wire wound exhaust hose, so no worries about them cracking or going flat with the bends Electric fuel pump fitted to replace the old mechanical one Piped up, but no sparks to it yet as I've ran out of relays Both the cooling fan, which I can now just squeeze in, and the fuel pump wll be switched through relays and have their own fuse box to keep things safe

Right, Additional fuses and relays to control the cooling fan and fuel pump And after much wrestling and a little more modification, I finally managed to get the fan fitted to the Rad As you can see, not much room, but i can just about change the alternator belt The fan isn't on a thermoswitch yet (It may never be!) but I have a switch mounted under the dash with a warning light to show it's switched on. I'm always watching the temp gauge anyways, so I don't anticipate any problems really Hopefully, tomorrow will be fillng it up with fuel, oil and water and getting a little tne out the old gal

Good to see this coming on. I have an electric fan on my Triumph GT6 wired up to a temperature sensor on the side of the radiator and the only time it cuts in is when it is on the rolling road or when sat in heavy traffic, so I would guess you probably won't have to switch yours on too often.
Do you know that the fan boss on the crankshaft is pegged onto the front pulley, so you could remove it to give you more space to move the electric fan lower if you want.

Do you know that the fan boss on the crankshaft is pegged onto the front pulley, so you could remove it to give you more space to move the electric fan lower if you want. I don't recall seeing a join in mine anywhere Besides which, it's all been balanced now, and if I start messing about with it, I should get it balanced again. That said, There may be more lightning and baancing work in the future! Anyways..... This weekend didn't prove to be as fruitfull as hoped The plan was to finish a couple of little bits, fill all the fluids and get a tune out the new lump. So, everything filled, battery connected, kids had refitted the gearbox cover, and cranking commences. Fuel pump ticking away, carbs filled up. Still no oil pressure tho (HT lead off) Then I spots oil running out of the bellhousing WTF ?!?! That's the end of play yesterday, cos we all threw our toys out the pram! lol I could only think of one thing. There must be a core plug missing from the oil gallery So, tonight I gets the car all stripped out, AGAIN, and low and behold, the b4stard plug is missing from the end of the main gallery! Properly angry with myself for not noticing that when I fitted the flywheel back plate, still I 'm also glad I noticed it when I did, and also glad that I was determined to see some oil pressure before going for a start! The good news to come out of this tho, is I can remove and re-fit the gearbox, clutch and flywheel in less than 2 and a half hours, single handed, which if you know how awkward some of these bellhousing bolts are on a straight six Triumph is no mean feat!

How annoying! But like you say, much better to have found out with no damage so that it could be sorted relatively quickly and cheaply.

There will always be problems but as you said glad you found it before running the engine and causing damage, looks proper smart now. Helped my dad put the head back on his vitesse convertible last weekend as the head gasket went last year and he had the head skimmed so we are a triumph family mind you he's also got a MK1 Zodiac he's putting back on the road and an Austin 7 in bits!

Well, it now runs, and i simply cannot describe the way it sounds, other than not too dissimilar to a tweaked up 13A rotary! lol
Not without problems tho,
Firstly the fuel lift pump wasn't working, so I had to get a new one of those, which is now mounted in the boot. Still need to get a fuel pressure reg tho, cos i'ts overfeeding the carbs and they're dribbling a little
That was after both carbs were curse word fuel out everywhere. This was found to be the needle valves in the float chamber fitted upside down. I kid you not, they were as taken out the new packet, I just didn't check them! *facepalm*
Anyways, she's now alive, spitting, banging and wailing like a Banshee!
Need some weaker needles for the carbs tho as it's still overfuelling with the jets screwed all the way up.
Video to follow (not got my data cable with me!)

That sounds amazing. ;D
BTW, is the ignition timing right? I'm sure you know this, but too much advance can cause all the symptoms of running rich.

I'm going to check the ignition tonight, but it was set static at 14deg BTDC so we'll see if it's moved any

Right, well, I've just spent the last hour and a half driving about Good news is that the radiator/electric fan conversion seems to be working very well indeed. The engine is sounding mechanically smooth and tight. Needs a bit of loosening off yet. It's damned tempting to put my foot flat to the floor, but I need to behave for a bit. Lol It really doesn't like going slow tho, or even driving at a constant speed. All it is happy doing is accelerating. I've yet to take it over 3.5k rpm or even use full throttle fully, but it's allready feeling quicker than the original engine. There's a lot of potential to be released yet, but first I need to get some steady miles on it and change the oil a couple of times. The fueling seems to need some tweaking to me. The carb springs are fine, there's no hesitation at all, but it feels as if it starts to lean out a bit when you get some revs on it and that cam starts to work, so I need to look at what needles are available, or start doing some custom profiles in the lathe Oh, and I also need to get some super unleaded in it, along with some Valvemaster plus Any which way, the first impressions are good ones ;D

Sounds like progress. ;D Oh, and I also need to get some super unleaded in it If the compression ratio's high this will make a big difference. As you know. Briefly: My car was running on regular unleaded, and showing signs of too much advance (rich and hunting idle, slight surging on over-run, etc.) - but when I put a timing light on it the spark was at TDC. 0 degrees advance. Oops. On V-Power, I was able to add a lot of advance (set up by feel). More power, more economy, easier starting, etc.

Sounds perfect, can wring some silly power figures out of Triumph 6s a guy round the corner from me used to hillclimb a MGC with a full race 2 litre Triumph engine, IIRC its doing the best part of 230hp. He took me down the road in it a few years ago its a proper rocketship. Flat out at 110mph but gets there without the accederation rate decreasing lol.

I'll be happy with somewhere between 130-150 tbh Anyways, having got about 100 miles under it's belt now, it seems to be settling down nicely. I've just added a fuel pressure regulator to hopefully stop the Carbs dribbling. I'm not convinced the ignition is as good as it could be, so I've ordered an Accuspark kit. Once that's fitted I can concentrate on adjusting the fuelling, cos anything over 3.5Krpm and she misses like a b@stard, so I'm convinced that whilst it's running nice at lower revs as soon as that cam starts to work it's leaning out way too much

When my Stag was misfiring but running smoothly at idle (most under load and above 3.5krpm (you could not accelerate past that point!) it was down to the new County branded coil I fitted (as 10mpg pointed in my post regarding cheap coils). Refitting the Bosch item cured the misfire. It did used to pop quite a bit from the exhaust with the cheap coil on mind you! In your case it could be the dwell angle (I have a Dwell meter you could borrow if you need to .

If the carbs are peeing everywhere then the level's too high in the float chamber. That will make the mixture richer.
Might it be the case that the fuel level drops when you get it on cam, leaning it out?

@ ChasR; Well, i'm currently running a Lucas 'Gold' coil. I guess that could be starting to break down, it's about 5 years old now. I've just fitted the Accuspark kit and I'll take it out for a spin later to see how it's doing. So far it's promising tho. It caught me out and started before I could let go of the key! lol. It's sounds a little better, so fingers crossed jrevillug; The rear carb only dribbles a bit when I leave the fuel pump running and the car not running. The car is also parked on a slight rearwards incline, so that might be contributing. The float levels are set spot on as per Burlens spec sheet that comes with the rebuild kit, but I may need to drop it slightly. @ mdh; You'll just have to wait till The Gathering at Prescot ;D

Well, todays' tinkering has resulted in a complete disapearance of the misfire that was starting around the 3300-3500 rpm mark. Result ;D It also now really feels like it's leaning out around the 4k mark, you can really feel the power drop off and exhaust note drop a little, where as it should be pulling strong and sound sharp. Definately not ignition problems, there's no missing, hesitation, backfiring or anything else, just a gradual fading out of power. I'm trying to get a few spare needles so I can have a play at reprofiling to help top end fuelling. Before I do that tho, I will pull the spark plugs tomorrow and have a look
