I've got a bottle of that ready to go in mine.

As for "we all do it" - I hope so :)

Considerably more comfy - in fact it may even be comfy enough to stay in there...

I still have this fuel issue to sort - I see no point in putting the engine in danger when it's not running properly :(

I agree.

I also found that the su's were ok with the pressure of the elec pump for a while but soon started to push fuel past the main jet while the pump was running.  

Not something you may notice if you were not looking for it as you would expect the fuel to come out of the overflow rather than the main jet.  Worth checking without the pistons or dash pots on.

BBT is what is in the carbs at the moment - I have the other two needles in my "stock"

You are spot on about the pump - fuel is coming out the top of the jets... not good... should have ordered a regulator - but I have a Filter King ready and waiting to go on the Spitfire so I can use that (just would have been easier to avoid the filter bit and just shove it in-line)

When are we going to receive our info packs in the post?

Tim


Tim

I would have expected that you got them around Tuesday / Wednesday.  If anyone has not got an entry pack now, please will you make an entry and include your email address so that Tim Guy can see it and take action.  I will chase up anyone's pack that has not been recieved aswell.

Also see the MGoT Site

It says

GENERAL
Attached is the event guide for our Track Day at Castle Combe next Monday, 14th June. It contains all you need to know about the organisation of the day before you arrive. Please read it carefully.

Also attached are the MGoT Indemnity Form and a copy of the Session List, subject to any last minute cancellations necessitating any changes.

This information has been separately emailed to all participants this evening.

PLEASE ARRIVE IN GOOD TIME
Circuit access is available from 07:30. Sign-on will be open from 07:45 and the driver briefing begins at 08:30. Please arrive in good time, as we have 48 drivers to sign on. You will also need to have a static noise test, which is operating from 08:00.

PRINT OUT THE INDEMNITY AND BRING IT FULLY COMPLETED
You can help speed up sign-on considerably and reduce queuing time if you print out the MGoT indemnity form attached, and bring it with you fully completed. Please ask your 2nd drivers and passengers to do the same.

DON'T FORGET YOUR ROAD LICENCE
Please don't forget your full licence - both the plastic and paper parts if you have the newer type for all drivers. All cars must be road legal and conform to current MOT standards unless you have agreed otherwise with the MGoT committee in advance.

SESSIONS
The session list is also attached. We are running four sessions; three for MG and the other for Club Triumph. PLEASE CHECK YOUR SESSION ALLOCATION. The Red group is predominantly the less experienced drivers and/or slower cars. The Blue group is the more experienced drivers and/or faster cars, with the Yellow group the experienced group. More weighting is given to experience than the car's power! It is possible that we have the wrong driver experience level for you if you haven't updated your user profile recently. At this stage it is difficult to swap groups around if there are errors, but if you have a real problem in your session allocation, then please let me know and I'll see what we can do. The session running order on the day will be Red, Blue, Green (Club Triumph), Yellow.

PLEASE CHECK YOUR PRE-BOOKED INSTRUCTION OR HELMET HIRE
The Session List also shows the pre-bookings for instruction and helmet hire. Please check that these are correct.

ANY QUESTIONS?
Please feel free to email me or call me with any questions before the day.

I hope you all have a great day.

Best regards

I dont think the BBT's are rich enough.  My setup is similar to yours and when i went on the rolling road the guy put BAA in which was a little rich in the midrange for road use  (great for track use) so settled for BAB's

I have a filter king regulator and kept adjusting it with the pump on untill the fuel stopped flowing out of the jets.

Tim - could you tell me your engine spec when you had those installed?

I won't be able to get those needles in time now :(


James

2.5 pi (mk2 saloon) balanced bottom end, .20thou overbored, flat top pistons,  recess removed from block and matched piston heights, 10.1 compression, standard pi head, TR5 camshaft, 6-3-1 extractor manifold with single exit exhaust, lightened GT6 flywheel, HS6 SU's, electric "cube" fuel pump with filter king regulator.  131bhp and 149ftlbs torque.  I had the rolling road done about 2 weeks ago with about 500 miles on the fresh engine.

Thanks Tim.. mine is a 2 litre... 40 thou pistons... 11:1... ported head... wilder cam...

But - I think it still suggests that I do need richer needles!

James,

The dashpot springs have an effect too.  Can't remember which way round it works (lighter spring = richer mixture I think) do you know which you have?  Salisbury (Burlen) is almost on the way to CC  :P

Nick - am not sure! I guess I could just buy uprated ones but I don't think they would be causing that much of an issue. At least it's not my main problem.

Today I fitted a fuel pressure regulator, still didn't make any difference but solved the issue of fuel pissing out of the jets.

I was over at Picton's and we were scratching our heads as to what it might be - he suggested checking the float needle valves for size. Turns out I had one proper one and one that was too small. So we swapped them for a pair of fresh Jag ones. Still didn't seem to make much difference until I tried pulling the choke. This must have dislodged something as it then rev'ed very sweetly indeed! Before it was struggling to keep up - but now the fuel supply can keep up with the engine.

It's not quite a kick in the back yet - but it gets very fast very quickly now :)

So I'll clean out the jets tomorrow to make sure no more crud can come through and see how it goes.

Great to hear that you are making progress.  Are you going to get a RR session after you have run it in?

Right then- all set to go 8). Looking to hook up at mine for 07;00 with Tim and Sir Roy of Boy and get there for the official GT6 parking area at 07:30.
The giddy-o-meter is now bending the needle. Everyone else up and ready? :)

I took mine out today just to check it was all ok.

It was OK until i got back home and noticed the exhaust has started blowing ??)  It will have to do for tomorrow because i'll only bust it if i mess :B :B

I checked the throttle cable today and found that it wasn't quite opening fully following the replacement of the cable earlier in the week. This is now adjusted for FULL THROTTLE ;D ;D ;D ;D ;D
