Well it certainly worked for me.
Wonder what was actually causing the problem?

Regarding rechecking the float level to combat the problem of stopping, I have found two recomendations for float level, 11/32 and 7/16. What should I go for?

I was all ready to go down the injection route and then I found a Cure.
First of all remove the carb top and make another fuel inlet by drilling and tapping the opposite end. Tee the fuel pipe and have a double fuel entry to the carb.
Then Fit a High flow needle valve kit without filters.
This has transformed the car on track and I cant believe I suffered the problem for 7 years.
I dont think the double entry alone is enough but might be if you remove the small filters from the standard needle valves. High flow valves are cheap and available from the states.
This worked for me anyway.
I have tried the 600 carb on my 4.6, it made slightly less peak power but throttle response is MUCH better with the 500.
Im very pleased with my carburation and the only performance mods planned now are Merlin heads and maybe slightly larger dia exhaust.
Another mod worth considering is as I never needed to use the choke I removed the flap and spindle and also ground away the raised section that the flap sat on to ease flow into the carb.
