Actually, more like this

I'm guessing your car will have the original Lucas distributor like mine, a 25d4 model

I'll check on distributor and go from there, thanks for all the help. Maybe change generator out for alternator if any recommendations, or am I changing for the sake of change?

I'd definitely change to an alternator, I lucked out and got a Lucas one from a guy selling bits from his Lotus engined Cortina, so it was an easy fit. You remove the old voltage regulator as well, which is pretty straightforward. I'll see if I can find the links I used to understand the changes required, from memory it was from an Elan forum, there are lots more of these and it's a very common change.

None of my S4s have ever had the choke cable attached and I've been lucky that they've all been good starters with the right pre-start ritual. Get one that's not an easy starter and you've got flooded carbs and a smoking starter! Easy to install the cable and bits though.

As for ignition, the distributors on the Steel Bros car did change around so check what you've got befoer you order anything. Below is the solution I'm trying to figure out right now...

More issues arising, Came home after nightshift to find a small pool of gas under car, petrol dripping back out through throttle bodies. Upon further inspection I discovered that along with the mechanical fuel pump, I also have an electric one. The fuel pipe has a tee installed just before the mechanical pump, which feeds the electric one, and then tees back into the line after the mechanical pump, Im not a mechanic, but Im sure this cant be right? Looks like I effectively have 2 fuel pumps running at once (No wonder its a buggar to start)( Am I best to remove the mechanical pump completely (Blank off plate) and get a new electric one? (The existing electric one has seen better days) Im guessing the pump is designed to stop fuel flowing to carbs when vehicle is sitting? Any advice, Also the starter seems to jam occasionally, It is a Lucas M35J 10 tooth. After some research it appears that 9 tooth would possibly be better. I can get a M35g 9 tooth but its mounting centres are 127mm, Mine are approx 115mm. Im pleased Im not relying on this Lemon coloured thing for my daily transport! Thanks in advance for any advice that's not gonna cost me a bomb!

So your electric pump is in the front tee'd off the fuel line to the mechanical? It wont' like that, most pumps like to push not pull. I'd blank the mechanical pump with a plate from Burtons and put an electric pump under the gas tank at the back. Remember to get a low-pressure pump (3-4 psi) Don't get a higher pressure and try to strangle it down with a regulator - they seem to be so hit and miss. The benefit is that the lower pressure pumps that deliver enough for a Twink are cheaper anyway....

Can't help on starters sorry other than to say make sure the tooth count is compatible with your ring-gear. There is a popular Honda starter conversion that you can search online. When my starter failed, I had so many things fail at the same time (20 year hibernation) that I just went for a Roadrunner aftermarket high-torque unit so I' could quickly move on to the next item, which I think was alternator.... :-(

I did a write-up on using a Gemini starter:

Added bonus is they hit the starter ring gear from the other side, so if it's a bit worn you will get longer out of it.

Mine's still going well.
