Your explanation is pretty vague. Assuming that you mean the car started pinging when you say "not happy", about the only thing you could do with the carb to affect that is to richen the mixture. That in turn leads to other undesireable operating issues so isn't the best solution and may not be effective enough anyway.

"As expected the timing went off...." leaves me wondering what you're really trying to say. Lots of things to guess, but better info would be more usefull.
