So I've decided that it's not electrical but following on....
SInce my Cortina got it's life back I have been to the lockup and started it 3 times now. The last time, about 2 weeks ago, it started and had the nice little misfire with black and black sooty exhaust so I decided that the old FoMoCo carb was goosed, well it is 44 years old. I decided to bite the bullet, splashed out £200+ for a new toy and it arrived yesterday ( a day earlier than expected, FastRoadCar on ebay is the business). I couldn't fit it today 'cos the wife had something far far more important to do, going to get another tattoo!
So, here is my new bit of kit. A Weber 34 ICH and fitting kit.
Fingers crossed,.............again. If this works then I can fit the tank I got from SheffieldCortinaCentre <-- and bleed the brakes.(I'm hoping the master cylinder hasn't got any rust in it!)
ps: classiccarbs.co.uk is also very helpful but £10 postage vs Free postage was a no brainer so FRC it was.
