So, question for anyone who’s played around with the idle and transition port on HS series carbs. Just put together a husky 61/272XP hybrid. No porting (thinking about it), did some muffler work, other than that it’s essentially a stock saw. Got a HS254 carb on it at the moment. Something I noticed is the saw has a bit of a flat spot when going from idle to WOT. It’s subtle but definitely noticeable. If I open up the high speed a bit it goes away but then becomes too rich. I’m gonna play around with it some more, I’ve got a HS260 I could swap as well. I’m wondering if the idle and/or transition port mite need to be enlarged slightly? I can dial in the high and low to where the saw idles proper and has a nice four stroke around 12.5K but I get that flat spot. Thoughts?
