Eddy 1404 flooding

[Stagrover]

Hi I’ve been chasing poor running and idling for months on a rebuilt 4.6l Rover.

I’m using an offy dual plane manifold that was fine for 15years on a 3.9l with the same carb and distributor. I changed to sidecars suggestions on the needles and springs at the weekend without improvement.

I’ve just reset the float heights but found no improvement on a quick cruise round. I can’t detect any air leaks around the base and 4 hole heat spacer but decided to take the carb off and inspect the gasket in case there was an internal tear. No damage but it has revealed that the 2 front barrels and the left rear are all dry and using any fuel going in but the right rear is very wet for some reason.

I would, if possible, appreciate a layman’s explanation of what could be the cause.

Fuel consumption is getting worse probably explained by the excessive fuel getting into the wet inlet.

Thanks in advance

John

Having left the carb off overnight the “wet” manifold port is still wet and feels oily.

Can’t tell from smelling if it’s oil or antifreeze.

Any thoughts on identifying a source?

Has anyone heard from Sidecar recently? He seems to have taken a break from passing on his enormous practical experience?

This is what my 1404 is set up to run on my 4.6 (on dyno):
083 main primary jets
089 secondaries
6347 rods
Silver step up spring (which activates at 8 in hg of vacuum)
This is with big valve full race Buick heads, Scorcher dissy set at 10 degrees, Crane cam and Edelbrock inlet manifold.
