Hi all, I converted one of my 3500Ss to a weber 500 carb about 2 years ago, complete with facet solid state pump and filter king pressure regulator. The car has been in the workshop with the last 12 months, only being driven occasionally. I've found it very difficult to start the car if it's left stand for more than a week since fitting the weber. If it is used regularly it starts first attempt, no matter what the weather. The car also drives very well and returns excellent fuel economy. I've found that the choke makes no real difference to starting (and i've checked the linkage/cable is ok). My usual starting procedure is to pump the throttle 5/6 times and crank it over. However, after standing for more than a week, i have to repeat the procedure several times. When it does eventually start it idles roughly and i have to give it very careful throttle to gradually bring the revs up. If i try to rev it coughs and stalls. Once it has run for a few minutes it clears and runs perfectly, and will restart easily. Even after 24 hours it'll start first attempt. The carb was bought second hand, it came on a SD1 vitesse engine and box i bought. I left well enough alone, bolted it on, checked the fuel pressure, turned the key and it fired up. I haven't touched the mix since. The car has been driven about 600 miles since the conversion and once running never misses a beat, no smoke, no hesitation, and as i said good economy. The car always started on the button when it ran SUs, though these broke my heart on a regular basis! Has anyone else suffered these problems. Is there a specially starting procedure with the weber? Any ideas would be welcome.
One more item, when i plumbed the new fuel line i used a coil of micro bore copper 8mm pipe intended for water. I've since heard that copper pipe can split due to vibration if used on a car. What is the correct pipe to use? At the moment it is secured to the car with powder coated "P" clips normally used for FP200 fire alarm cable (these are a snug fit and have a hole for self tappers).
