Yeah, I've had that problem before and it sucks. My Youall PE28 works well after re-jetting as do most of the members here but over on Facebook almost everyone swaps in a Nibbi immediately. The Nibbi looks like a better made part to me and hopefully it will solve the hesitation issue.

Most PE28 ZS172 owners run 42/125 and the Nibbi guys recommend position #3 on the needle. I recommend starting at 1.5 turns out on the idle air screw. GL
