  1. I started the car today - what a difference! Beforehand, I had set the float level at around 16.5mm on the 7g floats and was getting an inconsistent and unreliable fuel level, but maybe around 30mm as far as I could tell. The engine was barely running, and sounded like a sack of hammers - it would reluctantly start, more or less idle without choke, but had to be very gently coaxed up the revs or it would cut out immediately, and was spitting back badly. It would cut out completely after about 5 minutes. I had balanced the carbs as best I could and improved it slightly, but it was terrib
  2. Thanks very much for the replies. The problem may be solved! Here's an update. I made a little wire frame to emulate how the carb lid holds the floats, filled the bowl to 27mm with a syringe and put the floats in the bowl on the wire frame. The floats (7g )sat around 11.5-12mm from top. It looks like to achieve a 27mm fuel level the float gap would need to be set to around 11.5-12mm, which is a long way off the recommended 14.5-15mm. However, I previously tried a 12mm gap several times and got inconsistent fuel levels from 26-28mm, but mostly around 28mm. My conclusion from all this
  3. I see your point, mine is the same. I was jacking the car a couple of inches at the back to get it level, but now I think about it that was maybe a mistake. Here's a quote from the article: 'Its important to do this (measure the level) on the car, as different fitments/manifolds give a different "angle" or rake to the carb, the main-jet stack must be supplied with a proper fuel level.' I took this to mean that the fuel level must be 27mm at the jet stack regardless of how the carbs are angled. It's the measurement at the stack that is key, regardless of what is happening elsewhe
  4. Hi Has anyone had any success with setting the fuel level in the carbs to 27mm from the top of the carb body as described here? http://sideways-technologies.co.uk/forums/index.php?/topic/1048-setting-dhla-dellorto-dellorto-float-fuel-level/ Over the last 3 days I must have adjusted the float level and measured the resulting fuel level over 30 times, but I can't get consistent results. I'm having 2 problems: 1. Results are inconsistent - decreasing the float gap will sometimes increase the fuel level as expected, but sometimes not. Or I'll set the float level then re-check the resul
