eddy 500 overflowed - time for new carb?

hi guys, had a very scary moment today, my carb seriously overflowed and covered the inlet manifold in fuel. It cut out on a fast moving section of 3 lane bridge and all i could do was cost off at like 10 mph. So not good.

Anyway, its an old 10 yrs eddy 500> im not sure yet what spec rods are in it etc.

I know i could probably rebuild etc, but ive lost confidence in the unit and its getting on a bit, i think im gonna buy a straight replacement. It was RR at about 280 bhp, so i dont see any reason to go bigger than the 500.

The fuel pump is also an unknown quantity.

So where to go from here:

1) Get fuel pressure reg so i can adjust/monitor what the new carbs is being fed with?
2) my tvr spec fuel filter sits near the pump, should i have a second one closer to the carb?
3) identify the rods etc and just copy those onto the new unit? as it seems to run ok on these - then fine tune later down the road.

but i dont want a repeat of today!

Seems a bit much to replace the whole carb when all that has probably happened is that crap has got stuck in one of the float valves. I'd just give the carb a complete clean up and make sure that you have a decent fuel filter. AJMHO!

Sounds like you had a "sticky" needle & seat.

And you should have run it with a dialled in fuel pressure regulator. Something like a Filterking will work great.

Its quite relaxing to pull one apart and do an overhaul on the bench. I have my pressure reg in the engine bay and a pressure gauge tee'd into the rubber hose just before the carb. I also have a glass filter that I can clean myself as I like to keep an eye on grit. Just as well really because I've only put 20 gallons through the engine with Shell V Power from the same garage and theres a load of crap visible already. If your filter is at the other eng of the fuel system you may have a hose degrading and letting chunks loose after the filter? Stick a glass filter in next to the pressure gauge just near the carb ??
