Re: Poulan 3300 carb adjustments

Factory called for 1 on both L and H.  L was to be set using the lean and rich drop off points.  Mid point between and then a bit richer is getting close.  I find the HDA-49's on my 3000's are closer to 1 1/4 on the L and and a tad leaner than 1 on the H. 

As was mentioned, the factory impulse lines need checking.  The material for the line did not stand up to the heat at the cylinder base.  I have not seen one that hadn't become brittle.  Check the carb intake boot carefully for cracks as well.
