Late Carb Float Settings

robertjritter · Post by **robertjritter** » Sun Aug 28, 2011 12:28 pm

Does anyone have the correct settings for the late model carb? The service manual I have seems to only apply to the early carb.
I have fuel pouring out of the carb at idle. I assumed a float level that may have been set to high. I pulled the carb and measured the float setting from the center line and got 25mm. It definitely doesn't seem to high, but I can't seem to find the correct settings.
Any ideas?
Thanks!

I don�t have the setting but there might be a little something stuck in the jet and not letting it close.

Where is the fuel pouring out from? You may have a torn accelerator pump diaphragm, it is right under the bowl.

All gaskets are new. It's comeing from around the bowl gasket. This is only a problem about every 2 weeks. It's like the fuel level is too high and is soaking the bowl gasket. When I take everything apart and let it dry and put it back together I am good for another 2 weeks and then the same thing happens again. I wish I new what the correct float setting was. I'm tempted to set it lower anyways and see what happens. I have now completely flushed out the fuel system and cleaned and resealed the tank to try and get all of the old gas out in case that was the problem with the gasket. We'll see what happens in another two weeks...

In the Factory Coupe Shop Manual page 45 sub-section 5. Checking float level: Float level is 20.5mm. I can post a pic if needed.

Thanks. I'm hoping that it was just the old gas left in the lines that got to the bowl gasket causing it to fail. So far it is not leaking again...
Did the coupe use the same carb all the way through as the 72 Sedan?

Are you sure your float isn't taking on fuel?

2 carbs, you can see a number stamped on the body, top of body near where the rubber bellows screws on. The numbers are 718A or 718B. Differences are slight and there is a memo in the Honda Service Bulletins #14001 and Accel Pump info on #14002. Occasionally I have full sets of these bulletins avail for sale, but you might find them on Steven Michelsen's website or in the Photos section of this group.

Hi Miles,
My document goes up to bulletin 13-825. It does not include 14xxx.
#13-812 does discuss the accel pump - is this the one you were reffering to? It's page 15 in my file...
