Hey,

Just about to do an engine swap from my dying 1043 to a 3F engine, but ditching injection in favour of a weber carb (or pierburg depending on ££). So far I've got almost everything worked out apart from ignition (and vacuum stuff)...

Can I run the GT dizzy with an electronic ignition module from an MH engine (later mk2)?

Or do I need an MH dizzy with the vacuum advance on it and connect that up to the carb?

If someone can shed some light on this I would be very grateful. All the bits I can get from an MH in a local scrapyard but I'm leaving in an hour. Might just buy a dizzy and flog it on if not needed.

Cheers

Matt

GT dizzy doesn't have the mechanical advancing mechanism built in so you will need a mk2 dizzy

use a mk2 ignition amp and distributor from cars made after 1985.

Hes not using twin 40's I'm afraid

yeah I know after I read it again :shock: , but so many poeple seem to be asking about twin 40's and bike carbs these days.

Probably because induction noise is so good and ITBs cost too much!

Cool I got a distributor and ignition loom/module from a parade at the scrappy. Gonna get the old engine out 2moro once I can get to the driveshafts lol.

And yea lol screw all this bike carb/twin 40 stuff I'm just going for a single Weber.

The guy at the scrappy sold me a fuel pump for a tenner but it's probably going to put out a fair bit of pressure, I'll probably need a fuel pressure regulator won't I? Gonna be a Weber DMTL.

if you've got a fuel accumulator thingy on the side of the carb you should be able to get away without a pressure reulator

a "swirl pot"

Ah right ok. Will have to see when the carb arrives haven't got one yet

Why don't consider running the injection system ?

Can't be bothered with swapping looms/plugs etc (mine's an early mk2) and I like the sound a carb makes... plus I'm keeping it old school yo

Yea don't just connect the fuel pump straight to the carb.. you need some kinda fuel tank return system, either a swirl pot, or a t-piece with a restrictor in one end.

Ah so the Weber won't have a return pipe?

A T piece sounds like a good temporary measure to get it running, how does it work?! Sorry if it's a dumb question, I was gonna just connect it straight to the carb

some webers have a return and some don't. Golf ones usually don't have one so you have to get a swirl pot, available from gsf. Danny Lee should be able to dig out the part number for you. :)

use NZ/roco ign ....at least its hall not points............pm

how about D.I.S.

how about D.I.S.

lol its cool I got ignition side of things covered now, but thanks anyway. And gonna use a plastic swirl pot from scrappy until I can afford a metal shiny one hehe. Found the part number as well cheers.

when u say induction noise do you mean the piss annoying 'dyson syndrome' my carb engine has. sounds like my bloody hoover.

Probably because induction noise is so good and ITBs cost too much!

Why doesnt anyone make their own inlet manifold and mount a GT fuel rail (or other multipoint fuel rail) in it, then mount a knackered set of bike carbs on the other side that you can weld up and just use as 4 individual throttle plates. ITB's are expensive but knackered bike carbs, 4 steel tubes and an afternoons welding would give you change for a pint out of £20 I might do just as I've described after I've megasquirted my GT.
