2.4 Bridgeport carbs

[hotpony891]

I have a 2.4 Bridgeport motor with a 1989 stamp in the powerhead. The carbs are dumping fuel out the large hole on the face of the carb and the motor does'nt idle. I'm sure they need a rebuid and am wondering how much the cost would be. Also would like to know if these are the right carbs for this motor. Numbers stamped on the top carb are top left;13745427c, top right; WH, mid;157-155, throat;46 12358. The mid carb is stamped the same except by the throat which is 46 22738. The bottom carb is stamped the same as the top and mid except the throat which is 46 32748. Any little bit of info would help.

carbs are wh 46's. good carbs in my opinion.. there are better ones out there.. not sure if they came on a bp or not... somebody will chime in here. i will look for a chart i use to have..
more than likely a needle and seat problem.... cheap rebuild.. do all three of them!!!!!!!!

are you running a electric fuel pump?

Theres not much involved with rebuilding those carbs. A needle and seat is about it. If they are the original carbs, they will have slosh tubes on the top of each carb and should have plastic floats that usually dont go bad! They will also have baffle plates mounted inside each carb bowl with a single rivet holding it on. An old motor of mine had a rivet break and the baffle plate was laying on the float causing it to flood bad. You might want to check that out when you take them apart. Later___J.A.

Glad I have the better one's RWR,and they do have the tubes J.A. Holley Red is the fuel source. Any tricks to install those needle and seats? Also,a good cleaner to make these carbs look like new.

Not bad for a dollar.Anybody have any tips on how to repair the broken rivet for the baffle that J.A. experienced?

Just drill the old rivet out and pop a new one in. I recently got a 2.5 and it came with some WH-28's but I'm going to swap jets over to a set of 46's I have and use them instead. Sometimes the seat can loosen up and unthread which will cause the float not to rise and will flood that cylinder.

A problem I found lately is that the WH-28's I'm running will sweat like mad during casual runs. I can pop the cowl and the carbs are maybe 45 degrees to the touch and sweating condensation everywhere. From being a pilot I know that air passing through a venturi causes pressure to drop and air is accelerated while being mixed with fuel and that is what causes the temperature drop, the reason why we have carb heat.... but my 46's never used to do that. Anyone else ever notice this? I'm gonna swap over to the 46's and run them instead. I loved the way they ran on my 2.4.

I took apart the first two carbs,cleaned them up nice and installed new needle and seats and gasket set. When I started the third carb that's when I noticed the baffle/rivet broken. The pop rivet has a rounded head in the throat to prevent fuel from getting in. I probably could rivet it from the baffle side, but I'm not sure if the rivet would create a tight enough seal. Any feedback on this would be helpful.

I used a stainless rivet and it worked fine. Never had anymore problems. J.A.

[hotpony891]

Thanks J.A., I had a stainless rivet from Home Depot {was'nt sure which one to use} but installed the aluminiun before you posted, figuring the carb body is the same. I'll fill you in when firing this bad boy up.

Fuel was still dumping out. Then I changed to an old holley red and she runs like a charm. Do I need a regulator with this setup?

You should be running between 5 to 7 psi on a carb motor . My personal prefferance is 5 psi . Rich Martin 018;)
