I will leave the other answers to Andy but you don't use muffler pressure any more because you are now running a Walbro carb which has a fuel pump in it.
Not to nitpic but the website says it has a
Zama crab on it.
Yep, I ain't worried about the nitpicking, it's all in good fun. The ZAMA is the same, got a pump in it. I just didn't know they were called crabs. Look at the spelling.
