my ped uses to do this when it was cold

Only things I can think of is that if it's fitted with power valve maybe it's not opening up when should, also if a bigger carb you need to jet up to ur carb and air filter..

When you fitted the 34mm carb did you adjusted the oil pump ? Bigger carb and more 2 stroke oil...

clean the airfilter and the spark plug . and then find out where the mixture is ment tobe and things

different rev counter??? not seen tht before, PS, put some tights over the carb where the airfilter goes on, put the air filter on, over the tights, u only wanna try it folded 4 times n pulled tight, try that mate, i had bogging in mid range n tht sorted it, so was too much airflow n the tights reduced it, might not work but worth givin a go ay ;)
