Autosolo-ing and flooding carbs

Having just competed in my first autosolo it is a HOOT ;D, I really recommend them.
However it did show up some serious shortcomings in my car, namely the dellortos. They were surging and causing a VERY rich mixture with all th efast tight turns, my car was one of several that suffered, nobody had experienced it (or autosolos)before.
So I have now purchased an EFI system off fleabay, a complete setup off a Zetec, throttle bodies the lot 8)
So that should cure the carb problems. Now I just need to bolt it on and read up on Megasquirt. Sounds like fun!
Will post more once I have picked it all up.

PS I still beat Doug!

So easy you did it with your eyes closed, eh Clive? Superb! (clap)

Mind you, if you didn't beat the shed (wipe your feet getting out), there would have been a serious problem and much ribbing from Doug! :P LOL

Hopefully all this new stuff will make the car great for the RBRR. Only 67 days to go you know! ;D

the shed didn't do it self any injustice at all ..clive was only half a second ahead at the half way point ,but then managed to take an average of 3 seconds a run off me in th last four runs...i couldn't make the thing go any faster, the doorhandles would have fallen off it

Ah, but I was suffering serious slowness due to the carb problem, it even died completely on one test, and often firing on only 2 cylinders. Not very helpful! And I did completely cock up one of the tests with 2 fails. Ho hum.
Still, the kids were pleased with the "silverware" and I was rather surprised. Nice to get something.
And on for RBRR?? maybe, just depends on time. Can't really get round to anything for the next few weeks..... :P
Of course a hand may be errrr handy!

Hello Clive,

what is Autosolo?, from the description it seems similar to Autotests?

Are your carburettors flexibly mounted, i.e. with the double spring washers not compressed?

Autosolo:

Basically its like a Autotest, however one does the event without having to remember the route through the cones. A cone is used to mark a position/corner and another cone is laid on its side to act as a pointer for the correct direction past the cone. Therefore the contest becomes a test of ones ability to drive fast with precision.
Also when one is not driving it will be expected that all entrants act as a Marshal to view the other competitors and report the knocking over of a cone, this means time penalties are added to the time scored of the run. This economises the no. of people who have to Marshal.

I entered 'The Bocardo Autosolo' at Finmere near Buckingham back in May and had a great time. 5 CT entrants were present.

Ah, this one didn't have all the cones marked, and I seem to get directionally dyslexic :-/ hence 3 wrong tests. Oops. Also on this one we didn't need to marshall, so it helped speed things up a bit. But good hooning around, chews the tyres a bit 8)

Oh the carbs are correctly mounted, all double if not quad checked. It was not just my car, most of the weber/dellorto ones suffered, but strangely the fasted car there didn't. Work that one out.
Apparently it does happen, but it is down to the very tight corners at speed, with lots of sideways action. Fuel surges in the float chamber, ultra rich mixture. Do not ask me more tech details, thats all I needed to hear from the experienced crowd to reassure me. Hence the EFI kit I will be fitting, no more issues I hope! Road manners are still impeccable at all positions/speeds (except the stamp with the right foot which causes a fluff for a moment).
Goes to show how a damn good thrashing show up weaknesses in the car AND drivers!

Yep, I know I need swirl pot fed by existing facet red-top, then a high pressure pump, some sensors for air and water temp, a return fuel pipe and an air filter. Maybe socks. And some time to get my head round it.
Do I have to use an O2 sensor? my exhaust manifold has some mystery leaks (not bad, pass mot easily) but think that will affect the readings? Guuess I should sort it out properly :-/

That is a cheesy photo ;D
Only just noticed it, and the screwed up eyes. Laughing at Doug trying to take a photo. Not his strong point :P

I thought an autosolo was the same as an autotest but without having to reverse (the Herald was quickest in all the ones which required reversing!).

Sounds like you had it too easy at the Bocardo. I never had any of this cones on their side malarkey. :P

Clive, the O2 sensor is not essential but very nice to have (especially wideband).  Especially useful in the setting up stages - after that you can choose whether to allow it to have some control or turn it off.

You are right about the air leaks affecting things unfortunately.  I have this problem (again :() due the Pheonix 631 being absolutely determined to leak at the 3/1 joint whatever I do.  Best to seal the manifold properly if you can.

Think I will give up on my homemade jobbie and use the mondeo one I have in the garage, just meeds a new flange and it will be good to go. I think.
Its going to be a steep learning curve, Know of any good sites to get me started??

Yes, the Megasquirt one - it is truly excellent.  There is alot on there though...... :-/
Also worth having a look in the forum areas on that same site as there are some "How to" stickies

www.msefi.com

I'm going to have to relearn this myself shortly as I've promised myself a remap when I plonk the 'new' head on and add the wideband O2 sensor.  I've haven't messed with it properly for a couple of years so I'm beyond rusty  :P
