Update on Xflow Dizzy Problem
Can anyone please come up with a cheap solution to my 1300 xflow dizzy problem.
I'm gathering a ever increasing selection of dizzys and caps trying to get one to fit my Autosprint 1390 xflow running twin 40's.
Here's a list of things I've tried and checked so far.
1. Tried a Aldon dizzy (Lucas )with a side entery cap. No good, too tall and carbs will not fit.
2. Tried a Aldon dizzy with a much lower Austin cap(2 leads come out one side and 3 on the other) as recomended by Aldon. Still too tall.
3. Checked with the chap who I bought the carbs and inlet manifold off. He confirms that its the correct inlet manifold for a 1300 (angled upwards
giving more clearance) and he ran the carbs in question on his 1300 xflow powered kit car.
4. Checked with the chap who I bought the engine off. He ran a dizzy and twin 40's so I'm pritty sure the block and head have not been
skimmed too much reducing the clearence any further.
5. Gone down the Bosch dizzy route and got H&H to make me a special dizzy. They have shortened it by 2 inch's and altered the ignition curve
to suit my engine. Does it fit. Does it fuck. Managed to attach the carbs but unable to rotate the dizzy to alter the timing. Also catches on the
bottom of the spring return on the carbs so I'm unable to move the linkage fully.
I paid very little for the engine and did not want to have to spend loads of money sorting out the ignition system.
Please have a look at the pics attached and any solutions would be much appreciated.
Cheers
Chris

why not sell all the bits you have and as there must be a fair chunk of money sitting there and go megajolt and edis just done it on our pinto so much
better and the for bits cost aroud 20 quid the mega jolt is about 130 and general bits like connectors and a wiring loom kit and a proper mounting kit
with tps i would say it cost around 200 quid and a weekend to fit
you must have about 150 quid for all your dizzys and caps ect

Jolt and Edis, trigger wheel = big fat spark, 3d map, = sorted.
Or, just Edis, coil pack, trigger wheel = fixed 10 degree advance = still better than a dizzy...
Parts,
Megajolt
Edis 4
Coilpack - silvertop one is best, get the leads as well.
Vr sensor
Trigger wheel
Wiring and sensors from any zetec Mondeo or Focus
Coil pack whacks out 60K spark, much fatter than a normal coil...
Then shift the carbs for some off a bike and your sorted!

Could the problem be the twin 40 Dellorto DHLA cards. Do they stick out more at the bottom cuasing the dizzy to catch.

Your going through them same issues as i did apart from mine was a 1600. See attached image and my dizzy was also bloody tight. I also ended up
getting h&h to shorten mine and it still only just fitted. But the thing i'm thinking of at the moment is, isn't the 1300 block
shorter than the 1600 block? Also, there is another manifold available at the same angle but is longer? So is the longer manifold meant to be for the
1300 as your manifold looks to be the same length as mine!
Just some thoughts
Cheers
Leon

Thanks for the reply. The block on a 1300 is shorter making it even tighter trying to fit the dizzy when running twin 40's but I've been
told its still possible to fit a dizzy.
The inlet manifold and carbs came off a 1300 and I've been told by the chap who I bought them off its the right one for the engine so still
unsure why it will not fit.
If anyone has a longer manifold going spare then please let me know.
Cheers
Chris

I never had a problem with my 1662Xflow and twin 40's, but then I am an old f^rt (technically speaking in terms of engine), and I did use a
Lotus twin cam dizzy, but, it did have the original lucas cap with side entry lead holes for COPPER leads with screw fixings inside the internal
contacts.
You might have to go 'old school' and use copper leads with suppressors.
just done a quick search and here you go (the 23D type is the one I'm on about)
Linky to cap pictures
Edit bit.
Not quite so big and nobbly at the top I think you will find.

A crappy shot of a 1300 crossflow in my Mallock.
This is a Triumph Dolomite cap and fits perfectly

What dizzy were you using with the dolly cap.
Spoken with H&H and they have sent me a pic of another cap that might give a bit more room.

A friend wondered if you are using a pre-crossflow weber manifold? The spacings are the same but the dizzy on a pre-crossflow is the otherwise of the
block.

I don't know if this helps - here are some photos of my setup. The engine is a 1600 crossflow with twin Dellorto 45s. The distributor has a
side entry cap. I don't know for certain what it is, but from the number on the rotor arm it looks like it could be a Lucas 45D4. If anyone
can confirm this I'd appreciate it! It's a tight fit, but there is just clearance under the carb.
Regards
Geoff

Update on dizzy problem
Thanks for the pics. Looks like a Lucas to me.
After taking the angle grinder to the mounting plate where the black box attatches to my Bosch dizzy and also taking some of the bottom of the inlet
manifold I finally got it to fit. Also had to shaved a bit of the top of the dizzy cap. So fingers crossed lets hope it all works and I've not
damaged anything in the process.
Cheers
Chris

Your life would be so much easier with megajolt. Here's what sits in place of the dizzy on my x-flow!
