The problem was the new carburetor was bad. I bought another new carburetor from ebay
We keep advising people to buy parts from real parts stores and not ebay / amazon for this exact reason
Lots of stuff there that has been rescued from the factory scrap metal bin then sold as "OEM"
SO another case of
"he who buys cheap pays twice "
Thanks for closing the thread and please get your parts from a dealer or one of the genuine on line stand alone specalist small engine parts retailers .
It will save you a lot of time & frustration is nothing else .
