Carried out some work on the mini today. I wanted to check the jetting and choke size of the weber carb, so I removed the carb and stripped it down.

Choke 40
Main jet 200
Air correction 180
Em tube F9
Pump jet 55
Idle 50 F8
Aux vent 3.5

From looking at the Vizard book this set up is listed for full race, I noticed that the pump jets where missing their gaskets, so I have ordered some. With this set up I have noticed that it bogs down below 2500 3000 and it has an erratic idle.

I'm going to try a lower setting/set up from Vizard on my weber and see how it goes, I also have on order a MED stub stack kit :)

I have just asked this question, but does any one know where I can purchase some Dunlop D93J tyres from?

Here's my new med stub stack for my weber dcoe 45

Hi guys

What could be causing this

I changed none of the settings (jets etc) in the carb, I only took it apart to check what the set up is. The only thing that has changed is the med stub stack.

It starts idles, but as soon as I try to rev it, it dies.

Any ideas?

Problem solved, nothing to do with the carb set up or air leaks, it turned out to be a fault with the stub stack itself.

On the itg back plate with the kit u can clearly see the larger hole for the float chamber.





When I lined up the lower section of the stub stack, you can see that the cut out had been milled in the incorrect position, which ment it blocked off the supply of air. I therefore had to take it to an engineering firm to mill it out correctly and with that it now all works :)

Yes the firm in question has been informed of the issue.

So the rally is almost here, tomorrow we are setting up service, noise test and the dreaded scrutineering! Then on Friday at midday it kicks off.

If you like you can keep track of my progress here

I will try and keep you updated on my progress and some pics.

Thanks for your comments:)

So all of the stickers have been applied, serivce set up, noise test and scrutineering all passed:)

When I got home I noticed that the rear exhaust hanger was looking very low! And yes I had caught the exhaust pushed it back and broke both of the cotton reel exhaust mounts lol so work to do even before the event has started.

10-12-2013

Well there's your problem!

10-13-2013

Well I have figured how this happened! And what makes it worse it was my ******* up!!!!!

I left the frigging dizzy shaft in place when I installed the blanking plug for the megajolt system. So it shifted from its correct position into the gearbox and then out the casing:(

I'm sure I'm not the first and won't be the last. At least I have another gearbox:)

So let the rebuild commence.

We completed 18 stages. We did all of the Friday evening and night stages and 4 stages Saturday morning and then we holed the gearbox on the end of stage 18. On the stage before a wire snapped to the coil and we only had 2 cylinders, so we had to do an on stage repair:)

It was great while it lasted, and was getting into the swing of things, but hey ho.

Bigger and better for next year, at least the rest of the car is ok.

10-16-2013

Not sure what damage has been caused inside te box. Not that it matters as I have a quaife dog-box to fit now and I think I will send the entire unit over to swiftune for a re-build this winter.

Hey guys

Looks like I'm going to need a new motor

I pulled the motor out and stripped it down and I was thinking that I only damaged the gearbox........nope.

There was more fretting on the crank and flywheel, damage to the con-rod, piston and block which was caused by the dizzy shaft. So with all that needing replacing, I think that a new motor is on the cards!

Who to use, I'm thinking of a short list MED, swiftune, Selby engineering or Harris Motorsport?

Can I have your thoughts on these builders, and maybe some recommended spec for around £3,000

2-28-2014

Here are some pics of the damage.

Crank fretting.....scrap


Damage to piston skirt and block


Damage to conrod

Now I know that I will need to replace the pistons and conrods, but what is your thoughts on the block and crank

7-16-2014

Hi guys

So here is the spec of my motor which I'm picking up in a few weeks :)

1380 MED race engine complete with Jack knight dogbox
Richard Longman custom split 45dcoe carbs

cooper s 521 polished/lightend/balanced rods
Ultra light flywheel and back plate

Gearbox

7-27-2014

Right guys, I've been over to guersney and collected the motor:) and a shed load of spares.



Massive ports



Equal length driveshaft kit



Every thing is looking good about this motor:) the carbs will need to be overhauled, who would you recommend?
So I will now start to look over a few things, it has a cam belt kit fitted C-AJJ3328 but it seems that no one stocks the cambelts:) replace the head gasket, check the clutch oil change etc.......oh and remove the dizzy shaft this time round.
