on the ea81, there are 2 small hoses that connect to the intake manifold.

 

first off of the heater hose pipe, there is a small one that connectes to the base of the carb mount.

 

second is one that connects from the intake manifold, just on the front side of the t-stat housing (the cold side) down to the little pipe that sticks out of the passenger side top of the block.

 

currently I have the weber water choke plumbed in line with the second hose listed above....

 

so I guess I need to know which way the coolant flows through that second hose...? (without unhooking a side to see :cool: ) I already know the first hose flow direction... but it was easier to plumb into the second one initially....

water chokes not good - best off with a manual

I don't know the flow tho

sorry

I do have another weber with a manual choke, but I just rebuilt this one, and it seems to work fine.... I just want to make sure it's plumbed in the best spot.....

whats wrong with water chokes? seems to be a good idea

problems with water chokes -

take WAYYYYY too long to open

get stuck easily

run rich for above reasons

if they break they can flood your engine - literally

sometimes never do and cause really crappy power loss

you have so much more control with a manual choke

I am probably biased because I overhauled an MG Midget with one and had to install a manual choke to get it to pass emissions, and before we did we had problems in all the afforementioned catagories save the choke blowing up (though I saw a junked car where that happened)

Graned it was not a Weber carb, but the principle has issues.

However you plumb it, make sure that water is flowing at all times, and that it is not governed by the thermostat.
