Ford V8 Carb

Hi boys, the boat has a Holly 4160 carb, a full service kit has been fitted and the floats set to the book specs. The reason this was done was the primary jets were dripping fuel at tick over and after the engine had been switched off and guess what? It still is, the cure has been to lower the float to about a quarter of an inch. In the many topics regarding bad tick over, it says check the float level. What is the level that anybody has used in the past that has worked? Or is the fault not related to levels? Holly carbs are new to me, Webbers, sus etc, no problems.,but this boat of my lads is giving me a head ache.
Its only the primary choke thats giving the problem at the moment, previous posts have been my son's and to be quite honest, couldn't change a bell on a bike!! Forgot to mention, this carb has internal float adjustments not the one with the external adjustment and the level hole in the side. Thanks, Geoff (its only the kids that think i'm grumpy)

Thanks for that, but i have swapped the needles and seats for the primary to the secondary, same result!! And the secondary isn't dripping. Having a low level won't be too bad because ther're only doing about 22mph and the secondary is only operating on initial pull out so feul starvation should only occur at a much higher speed, whch they can not afford to do which i £1 40 a litre nearly.

That's their way of saying idle Brian. When I was young, 15ish I had a Triumph motorcycle,they told you to wash the filter screens in parrafin, but wouldn't that just clog them up??? .Took me a long time to figure that out,parrafin was another name for kerosene.

It would be easier if they would just speak English!!

Geoff, I had the same issues you did and found that my fuel pump was putting out more pressure than the springs on the needles valves could resist. I did everything, bent float tabs,replaced needles and seats etc. The solution was a fuel pressure regulator, get one from 1 to 4 psi, not the high pressure regulators for fuel injected system.

Maybe useful.

Here is a US link, and you would need a local source,
