Carb float chamber gaskets

[Robin (UK)]

Hi All,

Is it possible to get carb float chamber gaskets without buying full rebuild kits?

I'm running twin carbs and both are a bit leaky, but I don't want to buy two kits if I can avoid it.

Thanks.

Robin.

Good question - short of cutting my own from gasket material, I'd love to know if anyone has found these?

Slightly off topic but if you coat new carburetor gaskets with a thin coating of silicone seal and let it dry the carburetor top can be removed without tearing the gasket, and the gasket reused. Just smear it on with your fingers and let it dry while you work on the carburetor. It stops the gasket from sticking.

Rusty-

I believe gas will destroy silicone sealant and cause it the swell and bubble up. Learned that on a Chevy LUV pickup way back when. It plugged the jets up as some of it got sucked up. Stupid on my part!

The darker colored top cover gaskets won't separate or fall apart from my experience on the B&B carbs. The newer white light colored gaskets will separate.

I just got one the other week from my "local better auto supply". They had it on the shelf with no need to order from the warehouse.

Only caution though: From the parts book there appears to be a couple of different numbers depending on the year and/or fuel pump. So you might want to take the float bowl or old gasket in to verify you are getting the correct size. http://www.ply33.com/Parts/group14#14-80-05

Not sure that having them on the shelf at an American auto parts store will help for you in the UK though Robin...

Edit: Oops. Answered wrong question. Don't know about carburetor float bowl gaskets...

Robin,

A bit of work would be involved to do what I propose, however, it may all be fixed afterwards. Take the Carb cover off place it over a piece of 1/4" or 1/2" plate glass to see if it is "true". Use that same piece of Plate Glass to check the true on the Carburator body (Bowl) top as well.

If the Carb parts rock around (are not flat/flush) then use different grits of sand paper on the Plate Glass to sand them flat again. Do not attempt this if too much metal has to be removed. I have found a small amount of rubbing it will do with a relatively fine piece of sandpaper to true up the surfaces. In this way the gasket you do install will no longer leak. When I rebuild Carburators I have used this trick with much success. Remember to keep everything clean while doings so and let no grit into the carb. I usually have the carb off and apart when doing this. It works but can seem like a lot of work. No more leaks are nice. I have done this with Carb Bases, Goose Neck Bases for Water Leaks etc. just trueing up surfaces that have warped slightly over time from heat is all thats happening here but is quite effective.
