Lots of interesting replies - thanks guys. I envy your Gewürztraminer John! Jugostran, I have the same thing with my cold starts, it usually stalls almost straight away but on a restart it is fine, although I find if the car is used a few days in a row this doesn't happen, interestingly my coolant is due a change.
Yes - my carb was brand brand new last year.
I've had a fairly in-depth look into injection November/December gone, I even planned and priced up a LPT turbo application, but I think this is a bit too far for the way things are right now - I'd need to change gearboxes, clutch and try and fit an intercooler in the front bumper as well as all the other stuff.
I stumbled upon a Megajolt (MJ) system last year that came off of a 205 GTI that had been converted to twin carbs, it came with everything - toothed timing disc that bolts to the the crank pulley, CPS with bracket, 205 engine loom modified for the MJ, Ford EDIS module, distributorless ignition coil, TPS and MAP sensors, thermostat housing (for CTS and coil mounting) and of course the MJ unit itself. It was very reasonably priced, so I just bought it! What I really want is a bit more torque (+/-power), ease of driving and economy. The easiest way to do that would of course be to get a different car, but that isn't why we're all here is it! As circumstances would have it, the GT is my daily at the moment and although I usually only drive to commute for 2 or 3 days a week at most, I'd like to improve and modernise it slightly.
I feel capable enough to fit the parts, the ECU comes with an initial start map which will need setting up properly, emerald do this with their rolling road including the different maps one can switch between. My plan for N/A EFI:
-Emerald ECU, which has an attractive switchable map feature, e.g. a power map and an economy map
-Distributorless 205 GTI thermostat housing for the correct ECU Coolant temperature sensor facility and coil mount for a wasted spark system.
-Injection downpipe for the lambda sensor (need a new downpipe anyway, mine is holy)
-Toothed crank wheel that bolts onto the crank pulley
-CPS and bracket
-Emerald air temp sensor (easy to retrofit into an induction pipe somewhere)
-Electric fuel pump (BX/205)
-205 GTI Inlet manifold (with fuel rail, throttle body, TPS and FPR)
-Possibly an injection BX air filter box etc depending on space
-Possibly even fit a 130bhp DKZ 205 cylinder head and cam (although as the pistons on the carb engines have no dish and other XU9 engines do, the compression ratio might be quite high and need the ignition retarding in certain circumstances).
OR I could just get the carb sorted, perhaps with an electronic fuel pump, FPR and the MJ for a bit more modernity. I really like this car and foresee keeping it.
This is where I should give a check list but it is decades since I had a carb engined car, a 1.6 Scirocco actually a super little runaround with a satisfying power surge when the second choke opened.
