I want to fit this carb to the dt engine but do I need to change all the jets first

it had a 142 main jet fitted I was told to use a 170 on the dt engine

I m unsure if I should also change the pilot jet it has a 45 fitted an do I also need to change the atomiser jet too the one fitted is 266OGk

Whew" dan,  that's a grey area,  it suck it and see really , I would fit a  TTO temp sensor on the spark plug,  so you know whats happening,

I did , on my 400.  its been a  godsend,   500 degree F. is the  terminal temp for 2 strokes,  , if you get it  about 300- 400.   YOU KNOW YOUR SAFE,
