Default Re: Carb sealing

I'm not a fan of the 'O' ring method. The rubber will swell and begin to deteriorate quickly. You don't want your engine injesting that stuff and it isn't a good seal because it cannot be clamped in except with hand pressure against the carburetor while installing it. Several members have also had the 'O' ring come loose and get sucked into the engine. Not good. Some suppliers offer a flat gasket, gasoline compatible, that will work better than standard rubber 'O' rings. I think you'll find that most silicone based sealants are not compatible with gasoline, (says so right on the package). There are some sealers that will do the job and if done correctly will not look like heck. When using a paste type sealant you want to fill the gaps (slots) where the throat of the carb attaches/clamps to the intake manifold as well as the entire surface of the intake where the carb goes.
This product is a little harder to remove but I've had good luck with Seal-All. It is a clear semi-liquid sealant and will take gasoline. Good luck. Let us know how you do.
