Sounds like you may have some debris stuck in your needle valve or the float is leaking causing the needle valve to remain open.

nobody ever has trouble until .... big_eek something goes wrong
did you check the float level while you had the top off?
have a good fuel filter on the line to the carb?

Check that the float isn't full of gas, the inlet needle valve is in good shape as is the seat and that the float pivot rod is not binding up on the float.

Your fuel pump wasn't touched... right?

I took the top of carb off, bowl was fill to top, float not binding, don't know much about carbs, gave the bottom of top piece a good bath with carb cleaner, letting it dry out, will put together later and try

Shake the float. If you hear sloshing the float needs replaced.
