I never got round to starting her last nite, because it was 9.30, and i didnt want to *yellow human water* off the neigbours.



However..... it started today , first time too! The clutch works properly now too, so i went for a little joyride to the top of my road

Thats the good news, the bad news is the RR/MOT didnt have time to do ther today, and the RR guys not in tomorrow, so it wont be going to bingly It's now booked for next friday. I could have got her mot'd somewhere else, but the main issue really is setting up the carb, i'm hoping it'll sail-ish, through its mot. At the moment, its idling lovely, you have to dial in about 2500rpm to move (i live on a bit of a hill tho), but it starts spluttering and wont really go any higher than 5000rpm but between 2500 and 5000 is well exciting And the gearbox all works lovely, and the drops whine nicely, not too loud... not too quiet

As matt said, the weber boxes dont have to be welded, i see a lot of people rivet them in. I used srews tho, because i've realised that hole there was quite convinient for messing behind the dash, so i wanted it to be easily removeable. I actually had a little.... er... 'discussion' with the guy about the hole, my argument being that original centre speedo minis had a hole there without the plate (hense why they're always rusty), he rekoned they had the plate there tho. Baaa

As for running it in, it'll get a little bit of running in on the rollers, and on the journey to said rollers... thats bout it. Obviously i'm not got go tearing out the MOT station bouncing it off the limmiter at every gearchange. But i ent gonna fa**y about, you stand more chance of glazing the pistons if you run it in too slowly than if you boot it all the time...apparantly. I'm sure Malcom (the RR guy) will advise. They know their stuff there, they're involved with all sorts of racing types, in the workshop they got a historic racing MG, a mini and something else, they got a mad spaceframed beetle thing, a tvr, a few autograssers and some other stuff i never saw that was in the trailers. They do all the race prep for customers, they do pit crew at some events, and they got a few of their own cars. So its alllllll good

Cheers for the comments

Got a bit of an update

Got it to the rollers today, drove it there... goes lovely above 3000rpm Its been on the rollers for 4 hours and still strugglin to sort out a big flatspot where there is absolutly no power till 3k. Something to do with the air speed or something? I think malcom must have tried absolutly every singe jet in his box, and he's even changed the 45 for a 40 with 30mm chokes, instead of the 36's it had before. Its getting better, and it certainly looked and sounded like it was better on the rollers, but after taking it for a spin it still wern't that great. Its much better than it was, but it aint great.

Of course its expected that its gonna be a bit flat before the cam comes in, but as it is, its a bit dangerous. When pulling off it crawls and bounces along very slowly till 3k and its easy to stall. The only other option is to pull off at 3k in a cloud of tyre smoke, not ideal!

For those who want to know its consistantly making between 75 and 80 at the wheels so far. His dyno's all analogue, no graphs or anythin, and it reads in mph on the guage, but glancing at the rev counter in the car it was at about 6500/7000rpm i think, or 100mph on the rollers guage anyway. Seems like there's more to come from it too, the needle on the bhp guage handnt reached its peak yet i dont think, it was still climbing at 7000rpm and showed no signs of stoping

Its still at the rollers, left it there and malc's gonna have another play tomorrow.

Bit gutted its still not done, but it is getting there... if not a little slow

I got no idea mate, may well be induction length, or the cam and head i ent got a clue. Maybe the demands of the slightly lumpier cam now need a longer manifold. I was thinkin that tonight acctually, and i mite mention it to him tomorrow, i would have thought he'd pick up on it tho.

I must admit that i find it a bit odd that barkers mini is runnin fine on a 45, all be it without the 1.5 rockers, yet mine is strangly running a bit betters on a 40, with more lift? :S He does have a 5 inch manifold tho maybe its the way forward? ..... hurmmmmmm

Well, finally, sorted the problem!

What a ball-ache it was to get there tho!
Malc called me up this morining having had someone else go to his to have a look. They had wound the dizzy up to 60deg advance, which made the initial 3000rpm much smoother, but in theory, it should be pinking its nuts off - but it wasnt. It lead them to believe that either the dizzys ********'d or the cam timing is way out.

So i went to malc's with a new dizzy and ignition system, thanks to oli. Tried it first, as that was easiest, and it didnt really get any better. So, instead, we decided to limp the mini home, tear it apart, and re-check the cam timing. Dispite the fact that i'd already checked it after last time it was out. To make sure it wasnt me doing anything wrong, oli checked it, and found it to be right on the mark, 105.75.

Decided to ring southam mini centre and see what they rekoned on the subject. Their advise was the 1.5 rockers where too much. Confused me a little, as the car came with 1.5's, and i didnt want to loose my top end power. But, at this point, we didnt have a lot to lose, so we but its back together with standard sintered rockers.

And now...... its goes, and it REALLY does go! Like a rocket! And to be honest, i dont think i've lost anything on the top end... i know its a fresh engine an' all, and the weber hasnt even been re-tuned since the 1.5's have come off, but i couldnt resist... but it got to 9000rpm in first before i changed and was still pulling Think a bit of self control will be in order for a while, but knowing what it's now gonna be capable of... its just imense.

Doesnt feel like a mini engine, its not as brutal as a 1380, its just an awsomly smooth power delivery, from somewhere between 3-4000 rpm... till whenever you decide to change gear

Dunno what to do about these 1.5 rockers now If anyone wants them, they cost me £260 new, and i'd like something close to that, bearing in mind the only mile's they've done have been on the rolling road. When i spoke to southam, they did say, they are by far the best you can get, its just a shame they are a bit overkill on my motor. I do want some proper 1.3 rockers tho, as sinterd ones are actually more like 1.2-1, and i dont think they're gonna last too long. I'm gonna speak to MED first and see if they can do anything to adapt them, but if anyone has any sensible offers, send me a PM.



Soz bout the essay, think it might be benifical for some to read tho, as 1.5's get talked about a lot, and this is an example where it seems, with the wrong cam, they are useless ... dammit! should have kept that lame ass 286scatter!
