Advice for getting the float bowl back on properly

Before replacing the gaskets, using fingers, coat the gaskets, very lightly, with white lithium grease. Then, insert the gasket into the upper groove of the carb housing. It should stay put there with the tack of the lithium grease. As Roger suggested, rotating the carb towards you helps a lot. Then, carefully insert the carb bowl into the housing groove. Final tip, once the bowl is inserted, gently snug it for a better seat. You may even hear a "click" when it bottoms out. Then secure the bowl with the bale wire. Don't forget to re-insert the carb into the rubber socket and tighten the screw clamp securely.

Thanks all for your replies, I went with Roger's suggestion and applied a tiny amount of lithium grease and got the gasket in place in the groove and it was then simple to push the bowl up and lock it in place. No leaks - yay.
